## Background
FIELD OF INVENTION
The present invention belongs to the area of cosmetics and refers to new ginger extracts in particular useful for skin and hair care products.
STATE OF THE ART
The stem cells, which are located near the hair follicles, are responsible for the gradually slowing down of the skin renewal system with aging. As a consequence the skin complexion changes from a luminous shine to a dull appearance, from a smooth to a wrinkled surface, from dense to thin skin (Grove et al., J Gerontol 1983, 38(2):137-42). The hair as an appendage of the skin is also affected by the aging of the stem cells: The hair colour is becoming grey to white, the hair structure is changing to a thin and fragile structure, the hair renewal is decreasing resulting in hair loss and baldness. It took years of research to locate the particular stem cell niches, to identify mechanism leading to a stem cell fade and to develop first ideas to protect the maintenance of these progenitor cells to proliferate and differentiate.
The hair follicle is a mini-organ which hosts four different stem cell populations in overlapping niches to keep a homeostasis in skin and hair integrity (Hodgkinson et al., Expert Rev Med Devices 2009, 6(6): 621-40). To ensure the maintenance of the stem cell populations the microenvironment of these niches is multi-faceted and can change suddenly due to injury but also progressively with cumulative alterations in consequence of UV irradiation and other external stressors (Fuchs, Cell Stem Cell 2009, 4(6): 499-502).
In the hair follicle, epithelial stem cells, in principle multipotent stem cells, are located in the bulge, forming hair follicle, epidermis, sebaceous gland, and apocrine gland (Tiede et al., Eur J Cell Biol 2007, 86(7): 355-76). Directly adherent to the epithelial stem cell population is the melanocyte stem cell population residing in the hair follicle bulge-subbulge area, the lower permanent portion of the hair follicle, to serve as a melanocyte reservoir for skin and hair pigmentation (Nishimura, Pigment Cell Melanoma Res 2011, 24(3): 401-10).
Keeping the stem cells of the skin, especially the stem cells of the bulge and bulge-subbulge area of the hair follicle, in a healthy status guarantees the maintenance of these stem cell populations to proliferate and differentiate and by this the maintenance of the skin and hair renewal system.
The hair follicle undergoes cyclical bouts of regeneration (anagen), degeneration (catagen), and rest (telogen) phase. The epithelial stem cell population in the bulge is synchronized with these phases forming the hair itself and the follicle channel. By the protection of the epithelial stem cell population the homeostasis of the hair follicle is given and aging phenomenons like hair loss, hair thinning, baldness and alopecia are prevented.
Genetic disposition as well as the natural aging process and/or disease contribute to hair loss and slower hair growth in both males and females. Approximately 50% of the population displays this trait to some degree by the age of 50, where thinning of the hair can begin between 12 and 40 years of age independent of gender (Otberg et al., Endocrinol Metab Clin North Am. 2007, 36(2), 379-398 and Price, Investig Dermatol Symp Proc. 2003, 8 (1), 24-27). Studies reveal psychosocial impact with hair loss to include body image dissatisfaction associated with negative stereotypes such as feeling older, weaker and less attractive (Pickard-Holley, Sem. Oncol. Nurs. 1995, 11, 235-238).
Agents which are able to stimulate hair growth by prolonging the phase of production of hair material and/or shortening the resting phase of hair follicles as well as to slow down or reduce hair loss are known as a cure for alopecia. Examples for agents stimulating hair growth by altering the hair follicle cycle are e.g. drugs; including Minoxidil (Rogaine), Finasteride (Propecia) and Dutasteride (Avodart) are approved treatments for hair loss. However, they require medical prescription, and are active only on a certain percentage of the population. Moreover, some of these drugs are not permitted to be used by females because of hormonal effects. Thus, premenopausal women should not take Finesteride due to the risk of abnormalities in male fetus when becoming pregnant (Krus et al., J. Appl. Cosmetol. 2007, 25, 59-74).
Minoxidil is a drug that is effective in inducing hair growth for a small percentage of patients and will re-grow hair only on top of the scalp. Adverse effects when taken orally are tachycardia, angina pectoris and fluid retention. When applied topically adverse effects are mainly dermatologic, i.e. local irritation, itching, dryness and erythema.
Other medical treatments available to treat hair loss include drastic surgical techniques such as scalp reduction, scalp flaps or follicular unit transplantation. These surgeries carry the risk of complications such as elevation of hairline associated with donor region, possibility of necrosis and unnatural appearance of hair growth direction, anesthesia and post-op care, not to mention high costs.
The alteration of the hair follicle cycle helps to retard the hair loss. But to protect from hair loss, hair thinning, baldness and alopecia the protection of the stem cell population is a sustainable mechanism. The onset of hair loss, hair thinning, baldness and alopecia is delayed when the epithelial stem cell population maintains the capacity to proliferate and differentiate, also known as sternness of the stem cells.
An incomplete maintenance of melanocyte stem cells in the bulge-subbulge area was shown to cause physiologic hair greying/canities through the loss of the differentiated progeny with aging (Nishimura et al., Science 2005, 307(5710): 720-4). A disturbed homeostasis of the melanocyte stem cell population is also known to result in pigmentation disorders like vitiligo and leucoderma although the mechanisms are not identified in detail. But it was already shown that the repigmentation of skin affected by the hypopigmentation disorder vitiligo is possible by the transplantation of functional hair follicle melanocyte stem cells (Vanscheidt et al, Dermatology 2009; 218(4): 342-3) to the affected skin.
By keeping stem cells in a healthy status and protect them against intrinsic and extrinsic stress factors, in particular by protecting them against apoptosis, the skin and hair are protected against aging and the hair against loss and greying. Therefore, the object of the present invention has been developing a new active that simultaneously protect stem cells in particular against damaging by UV radiation, and is useful for fighting the ageing of skin and hair, in particular against skin wrinkling, hair-greying, pigment disorders, hair loss and inflammations.
DESCRIPTION OF THE INVENTION
Object of the present invention is a new ginger extract, comprising
(a) 25 to 30% b.w. [6]-gingerol
(b) 5 to 10% b.w. [8]-gingerol
(c) 5 to 10% b.w. [10]-gingerol
(d) 1.5 to 4% b.w. [6]-shogaol
(e) 0.3 to 1.3% b.w. [8]-shogaol;
(f) 0.03 to 1 b.w. [10]-shogaol;
(g) 0.001 to 1% b.w. zingerone,
on condition that the amount of gingerols sums up to 35 to 50% b.w. and the amount of shogaols sums up to 1.5 to 6% b.w.
Another object of the present invention is directed to a ginger extract of the aforesaid composition, obtainable in that dried ginger leaves or roots are subjected to solvent extraction or supercritical extraction with carbon dioxide.
In a preferred embodiment the ginger extract shows a total content of pungent components (gingerols+shogaols+zingerones) of about 42 to about 50% b.w., preferably about 43 to 47% b.w. and a content of essential oil of less than about 5% b.w., preferably less than about 2.5% b.w.
Surprisingly the ginger (Zingiber officinale) root extract characterized by a high content of pungent components according to the present invention is capable to protect stem cells, more particular stem cells of the hair follicle stem cell niche against UVB irradiation and maintain their activity. The ginger extract according to the present invention is additionally a potent anti-oxidant and a potent anti-irritant agent. Thus, the ginger extract according to the present invention is a protector against aging, pigmentation disorders, hair greying and hair loss and thus an agent capable to support well-aging of skin and hair.



BRIEF DESCRIPTION OF THE DRAWING
The present invention will be described in greater detail with reference to the accompanying drawing in which FIG. 1 illustrates an HPLC chromatogram obtained for a ginger extract according to the present invention (ginger extract 30 mg/10 ml EtOH, detected at 280 nm) with peak at 27.1 min: 6-Gingerol, peak at 33.4 min: 8-Gingerol, peak at 34.5 min: 6-Shogaol, peak at 39.0 min: 10-Gingerol and peak at 43.0 min: 12-Gingerol.



DESCRIPTION OF THE PREFERRED EMBODIMENTS
Ginger Extracts
Ginger root extracts with a high content of pungent components are well-known for the flavouring of food and beverages. The characterization of ginger root extracts by HPLC, GC and other analytical methods is well-described. The quantification of pungent components like gingerols, shogaols and zingerone is good laboratory practice. But ginger extracts characterized by a high content of pungent components of 42-50% b.w. have not been described for cosmetic applications before.
The water and/or ethanol and/or water/ethanol extracts of ginger root of unknown composition are described as anti-oxidants and anti-aging agents and are often disclosed as the preferred extracts for these applications. The use of these extracts is described inter alia in JP 2009 073777 A1 for the improvement of wrinkles, in JP 2000 319189 A1 as elastase inhibitors, by Fujimura et al. (Fragrance Journal (2002), 30(6), 38-42) for wrinkle improvement by inhibition of elastase activity. In JP 2007008847 the claimed extract was prepared with 20% ethanol resulting in the concentration of fructosyl dipeptides as active principles.
For the application to hair and scalp ginger tincture, ginger juice and the above mentioned water and/or ethanol and/or water/ethanol extracts of ginger root are well-known. As activities for these extracts on hair and scalp inter alia enhanced microcirculation is described. For example, CN 102451128 A1 suggests a shampoo claimed to prevent hair loss contains 5% ginger juice. JP 63 091315 A1 describes microcirculation enhancing ginger juice in shampoo formations for hair growth stimulation. EP 1281402 B1 (Kao) refers to a ginger extract substantially free of gingerols for hair growth inhibition.
Ginger oil was used as a soothing, relaxing or warming agent in cosmetic formulations in WO 2009 087578 A1 (Foamix). But the document did not disclose the composition of the ginger oil. The essential oil of ginger is known for a strong pungent smell and taste due to the volatile constituents and is not comparable to the ginger pungent extract according to the present invention.
The isolation of the pungent components of ginger is described in different documents. Ficker et al. (Phytotherapy Research (2003), 17(8), 897-902) evaluated the anti-fungal activity of ginger constituents.
The evaluation of anti-inflammatory activity of pungent components of ginger was given in different documents, inter alia by Lantz et al. (Phytomedicine (2007), 14(2-3), 123-128). Additionally the anti-tumour activity and proliferation inhibitory activity on tumour cells were evaluated by different groups, inter alia by Sang et al. (Journal of Agricultural and Food Chemistry (2009), 57(22), 10645-10650).
In CN 1840162 A1 a ginger root CO2 extract is described without specifying the content of pungent components like gingerols and shogaols. The extract is disclosed as an anti-inflammatory extract. Application examples are tablets, pills and capsules for oral consumption. Examples for topical application on skin are not described.
Extraction
The ginger extract according to the invention is preferably extracted of the dried ginger (Zingiber officinalis) root (rhizome). The product is prepared by supercritical fluid extraction with natural carbon dioxide or a solvent mixture of comparable polarity. Due to a fractional supercritical fluid extraction the pungent components of ginger are enriched.
Another object of the present invention refers to a process for obtaining the new ginger extract, wherein

    (a) ginger roots are frozen at about −10 to about −25° C.,
    (b) the frozen roots are shredded, cut and dried at about 20 to about 50° C. for about 10 to about 30 hours,
    (c) the dried roots are subjected to supercritical extraction with carbon dioxide at about 25 to about 90° C. and about 220 to about 370 bar for up to 10 hours; and
    (d) the extraction product obtained after about 3 hours is collected while the forerun taken from the first three hours is dismissed.


More particular ginger root is frozen at about −15 to about −20° C. The frozen ginger is shredded and cut. Afterwards the material is dried at about 30 to about 40° C. for about 15 to about 25 hours using a continuous flow dryer. The supercritical fluid extraction is performed with carbon dioxide at about 35 to about 50° C. and about 250 to about 350 bar for up to 10, preferably up to 7 hours. The flow rate is within the range of about 10 to about 20 kg CO2/h*kg raw material. The extract of the first fraction in the first 2 to 3 hours is dominated by essential oil after the de-pressurizing process. The extract of the second fraction taken from 3 up to 7 hours from the starting is the extract according to the present invention after the de-pressurizing process.
Pungent components of ginger extract are in means of the present invention gingerols, shogaols, zingerone, gingerdiols, dehydrogingerdiones and paradols.
The extract is characterized by about 42 to about 50% total pungent compounds mainly gingerols and shogaols with the proviso that extract comprises less than 6% shogaols. The content of zingerone in the ginger extract according to the present invention is lower than 1%.
The advantage of the ginger extract according to the present invention is the low content of essential oil with less than about 5% b.w., more preferable less than about 2.5% b.w. Several components of the essential oil of ginger are known skin sensitizers, by way of example citral, citronellol, eugenol, geraniol, isoeugenol, limonene and linalool. By way of example the skin sensitizers citral, Linalool, Citronellol and d-Limonene are limited due to the production procedure to a concentration of about 0.7% b.w., 0.2% b.w., 0.07% b.w. and 0.3%, b.w. respectively.
Due to the low content of essential oil the ginger extract according to the present invention has no to negligible odour when incorporated in a cosmetic formulation in concentrations sufficient to protect stem cells in the skin.
The ginger extract according to the present invention is a brown clear oily liquid with negligible pungent smell and taste.
By the extraction procedure and the resulting enrichment of pungent components a high content of lipophilic components is combined with a low content of essential oil. By this the ginger extract according to the present invention is beneficial with regard to the potent stem cell protection properties and also with regard to negligible smell and with regard to a low sensitizing potential.
Cosmetic Compositions

The fatty acid amide derivative known under the CTFA name of Cocamidopropyl Betaine is particularly preferred. Ampholytic surfactants are also suitable emulsifiers. Ampholytic surfactants are surface-active compounds which, in addition to a C8/18 alkyl or acyl group, contain at least one free amino group and at least one —COOH— or —SO3H— group in the molecule and which are capable of forming inner salts. Examples of suitable ampholytic surfactants are N-alkyl glycines, N-alkyl propionic acids, N-alkylaminobutyric acids, N-alkyliminodipropionic acids, N-hydroxyethyl-N-alkylamidopropyl glycines, N-alkyl taurines, N-alkyl sarcosines, 2-alkylaminopropionic acids and alkylaminoacetic acids containing around 8 to 18 carbon atoms in the alkyl group. Particularly preferred ampholytic surfactants are N-cocoalkylaminopropionate, cocoacylaminoethyl aminopropionate and C12/18 acyl sarcosine.

D. Superfatting Agents and Consistency Factors



Superfatting agents may be selected from such substances as, for example, lanolin and lecithin and also polyethoxylated or acylated lanolin and lecithin derivatives, polyol fatty acid esters, monoglycerides and fatty acid alkanolamides, the fatty acid alkanolamides also serving as foam stabilizers.
The consistency factors mainly used are fatty alcohols or hydroxyfatty alcohols containing 12 to 22 and preferably 16 to 18 carbon atoms and also partial glycerides, fatty acids or hydroxyfatty acids.

P. Enzyme Inhibitors
Suitable enzyme inhibitors are, for example, esterase inhibitors. These are preferably trialkyl citrates, such as trimethyl citrate, tripropyl citrate, triisopropyl citrate, tributyl citrate and, in particular, triethyl citrate (Hydagen CAT). The substances inhibit enzyme activity, thereby reducing the formation of odour. Other substances which are suitable esterase inhibitors are sterol sulfates or phosphates, such as, for example, lanosterol, cholesterol, campesterol, stigmasterol and sitosterol sulfate or phosphate, dicarboxylic acids and esters thereof, such as, for example, glutaric acid, monoethyl glutarate, diethyl glutarate, adipic acid, monoethyl adipate, diethyl adipate, malonic acid and diethyl malonate, hydroxycarboxylic acids and esters thereof, such as, for example, citric acid, malic acid, tartaric acid or diethyl tartrate, and zinc glycinate.
Q. Odour Absorbers and Antiperspirant Active Agents
Suitable odour absorbers are substances which are able to absorb and largely retain odour-forming compounds. They lower the partial pressure of the individual components, thus also reducing their rate of diffusion. It is important that perfumes must remain unimpaired in this process. Odour absorbers are not effective against bacteria. They comprise, for example, as main constituent, a complex zinc salt of ricinoleic acid or specific, largely odour-neutral fragrances which are known to the person skilled in the art as “fixatives”, such as, for example, extracts of labdanum or styrax or certain abietic acid derivatives. The odour masking agents are fragrances or perfume oils, which, in addition to their function as odour masking agents, give the deodorants their respective fragrance note. Perfume oils which may be mentioned are, for example, mixtures of natural and synthetic fragrances. Natural fragrances are extracts from flowers, stems and leaves, fruits, fruit peels, roots, woods, herbs and grasses, needles and branches, and resins and balsams. Also suitable are animal products, such as, for example, civet and castoreum. Typical synthetic fragrance compounds are products of the ester, ether, aldehyde, ketone, alcohol, and hydrocarbon type. Fragrance compounds of the ester type are, for example, benzyl acetate, p-tert-butylcyclohexyl acetate, linalyl acetate, phenylethyl acetate, linalyl benzoate, benzyl formate, allyl cyclohexylpropionate, styrallyl propionate and benzyl salicylate. The ethers include, for example, benzyl ethyl ether, and the aldehydes include, for example, the linear alkanals having 8 to 18 carbon atoms, citral, citronellal, citronellyloxyacetaldehyde, cyclamen aldehyde, hydroxycitronellal, lilial and bourgeonal, the ketones include, for example, the ionones and methyl cedryl ketone, the alcohols include anethole, citronellol, eugenol, isoeugenol, geraniol, linaool, phenylethyl alcohol and terpineol, and the hydrocarbons include mainly the terpenes and balsams. Preference is, however, given to using mixtures of different fragrances which together produce a pleasing fragrance note. Essential oils of relatively low volatility, which are mostly used as aroma components, are also suitable as perfume oils, e.g. sage oil, camomile oil, oil of cloves, melissa oil, mint oil, cinnamon leaf oil, linden flower oil, juniperberry oil, vetiver oil, olibanum oil, galbanum oil, labdanum oil and lavandin oil. Preference is given to using bergamot oil, dihydromyrcenol, lilial, lyral, citronellol, phenylethyl alcohol, α-hexylcinnamaldehyde, geraniol, benzylacetone, cyclamen aldehyde, linalool, boisambrene forte, ambroxan, indole, hedione, sandelice, lemon oil, mandarin oil, orange oil, allyl amyl glycolate, cyclovertal, lavandin oil, clary sage oil, β-damascone, geranium oil bourbon, cyclohexyl salicylate, Vertofix coeur, iso-E-super, Fixolide NP, evernyl, iraldein gamma, phenylacetic acid, geranyl acetate, benzyl acetate, rose oxide, romilat, irotyl and floramat alone or in mixtures.
Suitable astringent antiperspirant active ingredients are primarily salts of aluminium, zirconium or of zinc. Such suitable antihydrotic active ingredients are, for example, aluminium chloride, aluminium chlorohydrate, aluminium dichlorohydrate, aluminium sesquichlorohydrate and complex compounds thereof, e.g. with 1,2-propylene glycol, aluminium hydroxyallantoinate, aluminium chloride tartrate, aluminium zirconium trichlorohydrate, aluminium zirconium tetrachlorohydrate, aluminium zirconium pentachlorohydrate and complex compounds thereof, e.g. with amino acids, such as glycine.

The amounts of cosmetic or dermatological auxiliary agents and additives and perfume to be used in each case can easily be determined by the person skilled in the art by simple trial and error, depending on the nature of the particular product.
The preparations can also contain water in a quantity of up to 99% b.w., preferably 5 to 80% b.w., based on the total weight of the preparation.
Pharmaceutical Compositions
Another embodiment of the present invention refers to a pharmaceutical composition comprising the new ginger extract, containing the extract in an amount of from about 0.01 to about 1, preferably from about 0.1 to about 0.5% b.w.—calculated on the total composition.
Pharmaceutical compositions according to the present invention may include similar additives as already explained for the cosmetic application, such as for example oil bodies or emulsifiers and in particular co-actives supporting the beneficial properties of the new ginger extracts. It should also be mentioned that several actives cited in the following can also be incorporated in cosmetic formulations, so-called “cosmeceuticals”. Therefore, the border between cosmetic and pharmaceutical compositions is in flow and it should be understood that components cited for one application are recommended for the other mutatis-mutandis without literal repetition.
A. Anti-Irritation Agents
An important group of co-actives encompass anti-irritant agents such as for example steroidal anti-inflammatory substances of the corticosteroid type, such as e.g. hydrocortisone, hydrocortisone derivatives, such as hydrocortisone 17-butyrate, dexamethasone, dexamethasone phosphate, methylprednisolone or cortisone; non-steroidal anti-inflammatories like oxicams, such as piroxicam or tenoxicam; salicylates, such as aspirin, Disalcid, Solprin or fendosal; acetic acid derivatives, such as diclofenac, fenclofenac, indomethacin, sulindac, tolmetin or clindanac; fenamates, such as mefenamic, meclofenamic, flufenamic or niflumic; propionic acid derivatives, such as ibuprofen, naproxen or benoxaprofen, or pyrazoles, such as phenylbutazone, oxyphenylbutazone, febrazone or azapropazone. Alternatively, natural anti-inflammatory substances or reddening- and/or itching-alleviating substances can be employed. Plant extracts, specific highly active plant extract fractions and highly pure active substances isolated from plant extracts, can be employed like extracts, fractions and active substances from aloe vera, Commiphora species, Rubia species, Rubus species, willow, rose-bay, willowherb, oats, calendula, arnica, St. John's wort, honeysuckle, ginger, chamomile, rosemary, sage, melissa, Passiflora incarnata, Sophora japonica, witch hazel, Pueraria, Dianthus or Echinacea, as well as pure substances, such as, inter alia, bisabolol, apigenin, apigenin-7-glucoside, rosmarinic acid, boswellic acid, phytosterols, glycyrrhizic acid, glabridin, licochalcone A, [6]-paradol, and anthranilic acid amides, such as, in particular, avenanthramides or dianthramides, are particularly preferred. The total amount of anti-irritants in a formulation or product according to the invention is preferably in the range of from 0.0001 to 20 wt. %, preferably from 0.0001 to 10 wt. %, in particular from 0.001 to 5 wt. %, based on the total weight of the formulation or product, respectively.
Particular useful co-actives are selected from the group consisting of anti-mycotica and pain relief agents, and more particularly the group consisting of erythromycin, dimetindene, betamethasone, ibuprofen, ketoprofene, diclofenac, metronidazole, acyclovir, imiquimod, terbinafine, docosanol, cyclopyroxolamine, and their mixtures:

    (I) Erythromycin is a macrolide antibiotic that has an antimicrobial spectrum similar to or slightly wider than that of penicillin, and is often used for people who have an allergy to penicillin.






    
    
        Recent studies have also shown that it can be used as a mild anti-depressant. For respiratory tract infections, it has better coverage of atypical organisms, including Mycoplasma and legionellosis. It was first marketed by Eli Lilly and Company, and it is today commonly known as EES (erythromycin ethylsuccinate, an ester prodrug that is commonly administered). In structure, this macrocyclic compound contains a 14-membered lactone ring with ten asymmetric centres and two sugars (L-cladinose and D-desosamine), making it a compound very difficult to produce via synthetic methods. Erythromycin is produced from a strain of the actinomycete Saccharopolyspora erythraea (see U.S. Pat. No. 2,653,899—Eli Lily).
    
    
    (II) Dimetindene, also known as Fenistil (RS-dimethyl(2-(3-[pyridin-2-yl)ethyl]-1H-inden-2-yl)ethyl)amine) is an antihistamine/anticholinergic used orally and locally as an antipruritic.






    (III) Betamethasone (8S,9R,10S,11S,13S,14S,16S,17R)-9-fluoro-11,17-(2-hydroxyacetyl)-10,13,16-trimethyl-6,7,8,9,10,11,12,13,14,15,16,17-dodecahydro-3H-cyclopenta(alpha)-phenanthren-3-one) is a potent glucocorticoid steroid with anti-inflammatory and immunosuppressive properties.






    
    
        Unlike other drugs with these effects, betamethasone does not cause water retention. It is applied as a topical cream, ointment, foam, lotion or gel to treat itching. Betamethasone sodium phosphate is sometimes prescribed as an intramuscular injection (I.M) for itching from various ailments, including allergic reactions to poison ivy and similar plants (see U.S. Pat. No. 3,053,865—Merck).
    
    
    (IV) Ibuprofen (RS)-2-(4-(2-methylpropyl)phenyl)propanoic acid) from the nomenclature isobutyl-propanoic-phenolic acid) is a non-steroidal anti-inflammatory drug (NSAID) used for relief of symptoms of arthritis, fever, as an analgesic (pain reliever), especially where there is an inflammatory component, and dysmenorrhea.






    
    
        Ibuprofen is known to have an antiplatelet effect, though it is relatively mild and somewhat short-lived when compared with aspirin or other better-known antiplatelet drugs. In general, ibuprofen also acts as a vasoconstrictor, having been shown to constrict coronary arteries and some other blood vessels mainly because it inhibits the vasodilating prostacyclin produced by cyclooxygenase 2 enzymes. Ibuprofen was derived from propanoic acid by the research arm of Boots Group during the 1960s and was patented in 1961. Originally marketed as Brufen, ibuprofen is available under a variety of popular trademarks, including Motrin, Nurofen, Advil, and Nuprin (see U.S. Pat. No. 3,385,886—Boots).
    
    
    (V) Ketoprofen (RS)2-(3-benzoylphenyl)-propionic acid is another one of the propionic acid class of non-steroidal anti-inflammatory drug (NSAID) with analgesic and antipyretic effects.






    
    
        It acts by inhibiting the body's production of prostaglandins (see U.S. Pat. No. 3,641,127—Rhone-Poulenc).
    
    
    (VI) Diclofenac is also a non-steroidal anti-inflammatory drug (NSAID) taken to reduce inflammation and as an analgesic reducing pain in certain conditions.






    
    
        The name is derived from its chemical name: 2-(2,6-dichloranilino) phenylacetic acid. In the United Kingdom, India, Brazil and the United States, it may be supplied as either the sodium or potassium salt, in China most often as the sodium salt, while in some other countries only as the potassium salt. Diclofenac is available as a generic drug in a number of formulations. Over-the-counter (OTC) use is approved in some countries for minor aches and pains and fever associated with common infections (see U.S. Pat. No. 3,558,690—Ciba-Geigy).
    
    
    (VII) Metronidazole (2-(2-methyl-5-nitro-1H-imidazol-1-yl)ethanol) is a nitroimidazole antibiotic medication used particularly for anaerobic bacteria and protozoa.






    
    
        Metronidazole is an antibiotic, amebicide, and antiprotozoal. It is the drug of choice for first episodes of mild-to-moderate Clostridium difficile infection. It is marketed in the U.S.A. by Pfizer and globally by Sanofiunder the trade name Flagyl, in Pakistan and Bangladesh also as Nidagyl by Star Laboratories, and in Thailand, as Mepagyl by That Nakhorn Patana. It is also marketed in UK by Milpharm Limited and Almus Pharmaceuticals. Metronidazole was developed in 1960. Metronidazole is used also as a gel preparation in the treatment of the dermatological conditions such as rosaceae and fungating tumours (see U.S. Pat. No. 2,944,061—Rhone Poulenc).
    
    
    (VIII) Acyclovir or acyclovir (USAN, former BAN), chemical name acycloguanosine (2-Amino-1,9-dihydro-9-((2-hydroxyethoxy)methyl)-6H-Purin-6-one), abbreviated as ACV is a guanosine analogue antiviral drug, marketed under trade names such as Cyclovir, Herpex, Acivir, Acivirax, Zovirax, and Xovir. The solid active agent has a solubility in water (20° dH) at 20° C. of less than 5 g/L.






    
    
        One of the most commonly used antiviral drugs; it is primarily used for the treatment of herpes simplex virus infections, as well as in the treatment of varicella zoster (chickenpox) and herpes zoster (shingles); see also U.S. Pat. No. 4,199,574 (Wellcome).
    
    
    (IX) Imiquimod (3-(2-methylpropyl)-3,5,8-triazatricyclo[7.4.0.0.2,6]trideca-1(9),2(6),4,7,10,12-hexaen-7-amine, INN) is a prescription medication that acts as an immune response modifier.

EXAMPLES
Example 1
Fresh ginger roots were frozen at −18° C. and afterwards shredded and cut. This material was dried at 30° C. for 17 hours using a continuous flow dryer. The dried material was subjected to supercritical extraction with carbon dioxide at 35° C., 250 bar and a flow rate of 10 kg CO2/h*kg raw material. A first fraction collected within the first three hours of the extraction process was discarded due to the high content of essential oil. A second fraction from 3 hours to 5 hours from the starting was collected after de-pressurizing process resulting in the ginger extract according to the present invention. 32 kg dried ginger root resulted in 1 kg ginger extract according to the invention.
The composition of the extract thus obtained is presented in Table 1. FIG. 1 shows a HPLC chromatogram of the extract.

COX-2-Assay
In Vitro
Cyclooxygenase-2 (COX-2) in the presence of test substance was mixed with the fluorometric substrate 10-acetyl-3,7-dihydroxyphenoxanin (ADHP) and Heme. The reaction was started by addition of the substrate arachidonic acid.
COX-2 converted the arachidonic acid into the prostaglandin endoperoxide G2 (PGG2). PGG2 was reduced to the corresponding alcohol PGH2. During this reaction ADHP resulted in fluorescent resorufin. Resorufin was quantified at an extinction wavelength of 535 nm and an emission wavelength of 590 nm.
The inhibition of COX-2 activity in the presence of test substances was calculated according to the following equation:

PGE2 Assay
In Vitro
Normal human epidermal keratinocytes (Lonza) are seeded in a 96-well microtiter plate at a concentration of 1.2×104 cells/well. Incubation for 20 to 24 h takes place at 37° C., 5% CO2, saturated humidity until growth to 50-60% confluency. Various concentrations of the test substances are applied to the cells in culture media. After incubation for 30 min the stimulation with 1 μM A23187 Calcium lonophor (except for an unstimulated control) is started. After another 30 min of incubation, 50 μL of the supernatants are taken for the quantification of PGE2 using the competitive ELISA (PGE2 Biotrak EIA System, RPN222, Fa. GE Healthcare).
The percent bound for each standard and unknown substance is calculated using the following equation:

Example 6
DCF Assay
In Vitro
Primary human dermal fibroblasts (Lonza) were seeded in a 96-well microtiter plate at a concentration of 0.5×104 cells/well. Cultivation took place at 37° C. and 5% CO2 in DMEM, enriched with 10% foetal calf serum. Confluence was supposed to be around 70% at the time, the incubation with the test substances began. Various concentrations of the test substances were applied to the cells in DMEM. After 24 h of incubation, 100 μL H2DCF-DA-solution (10 μM) incl. DAPI (1:1000) was added to all samples (excluded the background-control) and incubated for one hour to deesterify the H2DCF-DA by cellular esterases. The resulting H2DCF was thereby trapped inside the cell. After the incubation, the cells were washed and the prooxidant challenge was set (1 mM, 1 h). The resulting fluorescence was read at λex 504 nm; λem 524 nm. An increased level of ROS (reactive oxygen species) led to an increased amount of fluorescence.
The inhibition of the oxidation in the presence of test substances was calculated according to the following equation:

Example 7
Heme Oxygenase-1 Expression
In Vitro
NHDF (normal human dermal fibroblasts) cells were disseminated in a 6-well plate in a concentration of 2×105 cells/well (DMEM, 10% FCS). After cultivation in fully enriched medium (DMEM, 10% FCS) for 48 h at 37° C. and 5% CO2, the serum content was reduced to 0.1% to synchronize the cell cycle. Various concentrations of the test substances, the negative control (untreated cells) and tert.-butylhydrochinon as positive control, are added and incubated for a further 24 h. The maximum concentration of the test substances used corresponds to 0.2 times the value of the IC20 value of the cytotoxicity assay. After cell lysis, the protein amount was determined using the Biorad BCA assay. All samples were adjusted to the same protein level before application on a fast Criterion Gel (Biorad) to perform electrophoresis for 20 minutes at 300 V. Thereafter the proteins were transferred to a PVDF membrane on a semi-dry blotter (30 minutes, 25 V). The blotted membrane is blocked for 4 hours in a 5% milk powder solution in TBST at 4° C. After washing, the membrane is incubated with the first antibody solution HO-1 from abcam (1:500 in 1% milk powder in TBST) over night. After this, washing is repeated and the membrane has to be incubated for 1 h in the second antibody solution (goat anti mouse coupled to HRP; 1:800 in 1% milk powder). After washing, the membrane is exposed to chemiluminescence HRP-substrate solution for 5 minutes. The resulting band pattern is detected with a chemiluminescence sensitive camera system (Vilber Lou mat). The quantification was done by densitometry, using the Image J freeware software. The results are shown in Table 7:

Example 8
Hyaluronic Acid Assay
In Vitro
NHDF (normal human dermal fibroblasts) cells were disseminated in a 96-well microtiter plate in a concentration of 2×104 cells/well (DMEM, 10% FCS). After cultivation in fully enriched medium (DMEM, 10% FCS) for 48 h at 37° C. and 5% CO2, the serum content was reduced to 0.1% to synchronize the cell cycle. Various concentrations of the test substances and TGF-beta1 as internal standard are added and incubated for a further 72 h. The maximum concentration of the test substances used corresponds to 0.2 times the value of the IC20 value of the cytotoxicity assay. Hyaluronic acid is quantified by a competitive ELISA (TE-COmedical TE1017).
The percent bound for each standard and unknown substance is calculated using the following equation:

        A(blank):
        Absorption of the wells without antibody, without peroxidase conjugate
    
    


A standard curve is generated by plotting the percent B/B0 as a function of the log HA concentration. The HA amount in the unknown samples is calculated by interpolating from the percent B/B0 values to PGE2 concentrations.
