FIELD OF THE INVENTION 
       [0001]    The present invention relates to bioactive fractions and compounds from  Dalbergia sissoo  for the prevention or treatment of osteo-health related disorders. The present invention relates in the field of pharmaceutical composition that provides new plant extracts, their fractions and pure compound isolated from natural sources that are useful for the prevention and/or treatment of various medical indications associated with estrogen dependent or independent diseases or syndromes or disorders preferably in the prevention or treatment of estrogen dependent or independent diseases or syndromes or disorders caused in humans and animals, and achievement of peak bone mass during skeletal growth and health in humans and animals. Particularly the present invention further relates to the processes for the preparation of biologically active extracts, fractions, and isolation of pure compounds, from  Dalbergia sissoo  plant from the family Fabaceae their pharmaceutically acceptable salts and compositions of the principal aspect of the present invention. 
       BACKGROUND OF THE INVENTION 
       [0002]    Osteoporosis, which has been defined as a “state of low bone mass” is one of the major aging problems of the society. Osteoporosis is a metabolic disorder characterized by microarchitectural deterioration of bone tissue leading to enhanced bone fragility and consequent increase in fracture risk in older members of the population. Osteoporosis fractures occur most commonly in the spine, hip, distal radius and ribs. The risk is high in women as compared to men and increases sharply after 50 years of age. Factors predisposing towards osteoporosis include family history, genetic factors, hormonal factors, inadequate nutrition, and intake of certain medications, immobility and disease. The quality of life is greatly impaired in persons with sever osteoporosis. It is known to affect &gt;50% of women and 30% men over the age of 50 years. In women, there is also an accelerated rate of bone loss immediately and for variable number of years following menopause. 
         [0003]    Most of the pharmacological agents available for clinical use such as calcium, vitamin D and its analogue, calcitonin, bisphosphonates, raloxifene, hormone replacement therapy (HRT) etc. act by decreasing the rate of bone resorption, thereby slowing the rate of bone loss. Timely administration of such antiresorptive agents prevents bone loss. 
         [0004]    Hormone replacement therapy, though effective in preventing bone loss following ovariectomy or menopause in women, is associated with increased risk of endometrial hyperplasia and carcinoma [Grady, D. Grebretsadik, T. Ernestwr, V. Petitti, D.  Gynecol.  85, 304-313 (1995), Beresford S. A. Weiss, N. S. Voigt, L. F. McKnight, B.  Lancet  349, 458-461 (1997)], breast cancer [Riggs, L. Hartmann, L. C.  J. Med.  348, 618-629, (2003)], and thromboembolic diseases [Delmas, P. D.  Lancet  359, 2018-2026 (2002)]. 
         [0005]    The only side effect of calcium therapy is development of renal stones. The major disadvantage in calcitonin use is its high cost. Tachyphylaxis can develop in some individuals under calcitonin treatment. Bisphosphonates are poorly absorbed and may cause gastrointestinal irritation, diarrhea and constipation. Raloxifene has been reported to increase incidence of hot flashes, deep vein thrombosis, pulmonary embolism and leg cramps [Clemett, D.; Spencer, C. M.  Drugs  60, 380-409 (2000)]. 
         [0006]    In view of the use of these therapies and their associated side effects indicate a need for the alternative options in the prevention and treatment of osteoporosis. 
         [0007]    Traditional medicine is an ancient medical practice that existed in human societies before the application of modern science to health. The importance of traditional medicine as a source of primary health care was first officially recognized by the World Health Organization (WHO) in 1976 by globally addressing its Traditional Medicine Programme. In traditional medicine, there are many natural crude drugs that have the potential to treat bone diseases. However, not much laboratory work has been reported evaluating their possible development and use, except ipriflavone, a natural product derivative, which has been used clinically for such indications [Fujita, T.; Yoshikawa, S.; Ono, K.; Inoue, T.; Orimo, H.  J. Clin. Exp. Med.  138, 113-141 (1986), Passeri, M.; Biondi, M.; Costi, D.; Bufalino, L.; Castiglione, g. N.; DiPeppe, C.; Abate, G.  Bone Miner.  19 (Suppl. 1), S57-62 (1992)]. It is believed that herbal medicines are easily available, less expensive, and safer than chemically synthesized drugs. In India Ayurvedic medicine emerged during the rise of the philosophies of the Upanishads, Buddhism, and other schools of thought in India. Herbs played an important role in Ayurvedic medicine. In our program search for natural osteogenic plant, n-butanol soluble fraction of ethanol extract of  Dalbergia sissoo  aerial part which is renewable source exhibited osteogenic activity in our test model. Thus, the plant extract might possess bioactive ingredients that could promote bone formation. The effects on osteoporosis and total osteo-health and related disorders and has not been explored. 
         [0008]    There is a well-recognized link between the prevalence of low peak bone mass (PBM) attainment and osteoporosis among South Asian women [Adami, S.;  Osteoporos Int, Suppl  1, S27-30, (1994)]. PBM is defined as the highest level of bone mass achieved as a result of normal growth. Adolescence is the most critical period across the life span for bone health because more than half of PBM is accumulated during the teenage years. During these early years of life, bone formation is greater than bone resorption and the bone mass increases. PBM attained in early adult life is an important determinant of skeletal fragility at least until the age of 70 years (Ref). Following the attainment of PBM, resorption is faster than formation and the bone mass decreases. While gradual bone loss is normal to aging, it is those who fail to achieve optimal PBM and/or those with accelerated bone loss who are at the greatest risk of osteoporosis. In addition, low PBM predisposes to increased fragility fracture risk (Bonjour, J. P.; Chevalley, T.; Ferrari, S.; Rizzoli, R.  Salud Publica Mex.  51 Suppl 1:S5-S17 (2009)]. 
         [0009]    Therefore, since individuals with a high PBM at a young age are likely to have a high bone mass in old age, agents increasing PBM during skeletal growth is a desirable goal towards prevention of osteoporosis. PBM occurs several years after the completion of linear growth as bone mineral accretion continues after this time, although the precise timing of the attainment of PBM is not certain and varies between skeletal sites. A real BMD at the femur peaks around the age of 20 yr, whereas maximum total skeletal mass occurs 6-10 yr later, well after the cessation of the anabolic action of growth hormone (GH). Factors relating to the attainment of PBM include congenital, dietary, hormonal, physical activity, lifestyle, drugs and diseases. A therapeutic intervention aimed at increasing PBM has remained limited only to controlling factors such as estrogen status, dietary calcium intake and physical activity. Calcium intake appears to be relevant up to the so-called threshold intake (1000 mg/day), but higher allowances do not seem to offer additive advantages. Exercise affects only the regions of the skeleton under mechanical stress. Estrogen administration is realistic only in conditions characterized by severe hypoestrogenism. Clearly, nutritional deficiency is one of the major reasons for lack of PBM among South Asians, particularly among females those who are much more prone to bone loss at later stages of life. Therefore, agents that promote PBM have therapeutic implication for bone loss disorders. 
         [0010]    There is, thus, an urgent need to discover and develop a promising herbal product or a single biologically active molecule based drug or a cocktail of the pure and biologically active molecules of the plant origin that exhibit promising bone anabolic or for bone forming activity in experimental animals and human beings. The  Dalbergia sissoo  was a fit case to study and explore its true potential with respect to its bone forming response of its extract, fraction and pure biologically active marker components. The experiments have shown that its n-butanol soluble fraction and pure compounds isolated from the extract and the fraction exhibit promising bone forming activity. 
         [0011]      Dalbergia sissoo  Roxb. belongs to the family Fabaceae, is distributed throughout sub-Himalayan tract from Ravi to Assam ascending up to 5000 ft in India, Pakistan, Bangladesh and Afghanistan.  Dalbergia sissoo , commonly known as “Shisham” in India, is deciduous tree, having crooked trunk and light crown [Wealth of India. Raw materials, vol 3. CSIR, New Delhi, 1950.] An aqueous extract of the leaves of  Dalbergia sissoo  has been used for the treatment of gonorrhoea [Medicinal plants of India; S. K. Jain, Roberts A. Defilipps; 1991. vol-1, 325]. Leaves of the plant are bitter and stimulant and also used as fodder. Wood of  Dalbergia sissoo  was used for leprosy [R. N. Chopra, S. L. Nayar, I. C. Chopra. Glossary of Indian Medicinal Plants, 1956, page 90]. 
         [0012]    The methylene chloride extract of the heart wood of  Dalbergia sissoo  inhibited the production of β-amyloid peptides (Aβ) so it may have therapeutic potential in the treatment of Alzheimer&#39;s disease. A compound latifolin, isolated from the crude extract of the heart wood also inhibits β-amyloid production [Ramakrishna, N. V. S., Kumar Vijaya, E. K. S., Kulkarni, A. S., Jain, A. K., Bhat, R. G., Parikh, S., Quadros, A., deuskar, N., Kalakoti, B. S.,  Indian Journal of Chemistry  40B, 539-540, 2001]. Heartwood of the plant has also been reported to have anthelmintic activity [Manandhar, N. P.,  Fitoterapia  2, 149, 1995]. 
         [0013]    The ethanolic extract of the leaves of  Dalbergia sissoo  has anti-inflammatory activity [Hajare, S. W., Chandra, S., Sharma, J., Tandan, S. K., Lal, J., Telang, A. G.,  Fitoterapia  72 (2), 131-139, 2001] and petroleum ether extract also display the same activity due to a sterol i.e. sissosterol [Abdel-Ghani, Afaf, E., Dora, Gamal A.,  Mansoura journal of pharmaceutical science,  20(1), 104-113, 2004]. It has also been reported to possess antidiabetic property in alloxan-induced diabatic rats [Niranjan, P. K., Singh, D., Prajapati, K., Jain, S. K.,  International Journal of Current Pharmaceutical Science  2(2), 24-27, 2010]. The leaves of  Dalbergia sissoo  exhibit antipyretic, analgesic properties [Hajare, S. W., Chandra, S., Tandan, S. K., Sharma, J., Lal, J.,  International Journal of Pharmacology  32, 357-360, 2000] and also acts against diarrhea [Brijesh, S., Deswani, P. G., Tetall, P., Antia, N. H., Birdl, T. J.,  Indian J. Pharmocol.  38(2), 120-124, 2006]. The preparation of  Dalbergia sissoo  leaves has been used as an alternative herbal treatment for antimicrobial property [Yadav, H., Yadav, M., Jain, S., Bhardwaj, A., Shing, V., Parkash, O., Marotta, F.,  International Journal of Immunopathology and Pharmocology  21 (4), 1013-1020, 2008].

E., El-Gayed, S. H., Ameen, A.,  Al - Azhar Journal of Pharmaceutical Sciences  28, 285-299, 2001]. The bark has been also tested for antioxidant potential in an in vitro assay [Kumari, A., Kakkar, P.,  Biomedical and Environmental sciences  21(1), 24-29, 2008].

       EXAMPLES 
       [0237]    Following examples are given by way of illustration of the invention and should not be construed to limit the scope of the present invention 
       1. Extraction with Ethanol of  Dalbergia sissoo  Leaves 
       [0238]      Dalbergia sissoo  Roxb. belongs to the family Fabaceae, is distributed throughout sub-Himalayan tract from Ravi to Assam ascending up to 5000 ft in India, Pakistan, Bangladesh and Afghanistan.  Dalbergia sissoo , commonly known as “Shisham” in India,  Dalbergia sissoo  was collected from Lucknow, U. P. India. Lucknow is located at 26° 48′ North and 80° 54′ East. Powdered leaves of  Dalbergia sissoo  (Plant code No. 4744, 18 kg) were placed in glass percolator with ethanol (40 L) and are allowed to stand at room temperature for about 16 hours (overnight). The percolate was collected. This process of extraction was repeated for five times. The combined extract was filtered, concentrated at 45° C.; weight of extract obtained 2.00 kg (11.1%, 4744-A001). 
       2. Fractionation 
       [0239]    Ethanolic extract (4744-A001, 1.80 kg) was triturated with hexane (1000 ml×8). The hexane soluble fraction was then concentrated under the reduced pressure at 40° C., weight of hexane fraction obtained 427.0 g (23.7%, F002). Residue obtained after triturating with hexane was again triturated with chloroform (1000 ml×8). The chloroform soluble fraction was then concentrated under the reduced pressure at 40° C., weight of chloroform fraction obtained 333.0 g (18.5%, F003). The insoluble residue was suspended in water (2500 ml), extracted with n-butanol saturated with water ((1500 ml×7) ml). The combined n-butanol soluble fraction was concentrated under the reduced pressure at 45° C., weight of n-butanol soluble fraction δ40.0 g (41.1%, F004). 
       3. Isolation of Compounds from n-Butanol Soluble Fraction (F004) of  Dalbergia sissoo    
       [0240]    The n-BuOH fraction (600.0 g) was subjected to silica gel column chromatography (100-200 mesh), with the gradient of CHCl 3 -MeOH (90:10, 90:20, 70:30, 50:40, 50:50 and MeOH) as eluent. Six fractions (F1-F6) were collected according to TLC analysis. Fraction F1 was purified on silica gel column chromatography eluted with pure CHCl 3  afforded 13 and CHCl 3 -MeOH (95:5) to afforded compounds 1, 4 and compound 3 successively. Purification of F2 fraction by repeated column chromatography on silica gel eluted with CHCl 3 -MeOH (90:10 to 85:15) to afforded compounds 2 and 6. Purification of F3 fraction on silica gel followed by CC over Sephadex-LH25 and C18 column chromatography eluted with MeOH—H 2 O (30:70) afforded compounds 9, 7 compound 10 and compound 11. Fraction F4 afforded compound 12, compound 8 and compound 5 by CC over Sephadex-LH-25 eluted with MeOH—H 2 O (30:70), followed by repeated C18 CC eluted with MeOH—H 2 O. The flow chart for the isolation procedure is provided in  FIG. 1 . Accordingly butanol fraction afforded 13 compounds designated as 1-13. These compounds were characterized from detailed spectroscopic studies. The compound 10 is new reported for the first time from natural source. We have given the common name to 10 (Dalsissooside). The compounds 1-9 and 11-13 are known.

       5. Quantification of Active Principles in Alcoholic Extract (A001) and n-Butanol Soluble Fraction (F004) Designated as osteoNATURALcare 
       [0255]    The mother stock solution of the extracts was prepared by dissolving 2 mg of each dried extract (F004 and A001) in 50 μL dimethyl sulfoxide and volume than made up to 1 mL using methanol to get a solution of 2 mg/mL. 
         [0256]    The mother stock solutions of the active principles, namely 1, 3-5 and 10-12, were prepared by dissolving 1 mg of each compound in 50 μL DMSO and than volume made up to 1 mL using methanol to give a solutions of 1.0 mg/mL. Working standard solutions of all analytes were prepared by combining the aliquots of each mother stock solution and diluting with methanol. 
         [0257]    The samples were analyzed by injecting 50 μL of each sample on HPLC. The separation was achieved on C18 column using 0.2% acetic acid (A) and acetonitrile (B) as a mobile phase at a flow rate of 1 ml per minute. 
         [0258]    The concentration of components 1, 3-5 and 10-12 in n-butanol fraction (F004) and aqueous extract (A001) is given in following table-1

       6. Biological Evaluation 
       [0259]    The plant extracts and isolated pure compounds thereof were evaluated for the use of estrogen dependent or independent diseases or syndromes or diseases preferably in the prevention or treatment of estrogen dependent or independent diseases or syndromes or diseases caused in humans and animals, and achievement of PBM during skeletal growth and health in mammals. The activity testing illustrated in the following examples should, however, not be construed to limit the scope of invention. 
         [0000]    Treatment of n-Butanol Fraction (A-4744/F004) of  Dalbergia sissoo  in Ovariectomized Sprague Dawley Rats 
         [0260]    The study was conducted in accordance with current legislation on animal experiments [Institutional Animal Ethical Committee (IAEC)] at C.D.R.I. Immature Sprague Dawley rats weighing ˜180-200 gm were either bilaterally ovariectomized (OVx) or exposed to a sham surgical procedure. All rats were individually housed at 21° C., in 12-h light:12-h dark cycles. All rats had excess to normal chow diet and water ad libitum. After OVx, the rats were left for 12 weeks to develop osteopenia. After 12 weeks, extract treatment in the form of gavage (50.0 mg and 100 mg/kg body weight) and estradiol (EST) at a dose of 2.5 mg/kg bodyweight) was given daily. Equal numbers of OVx and sham operated rats served as the control, and were given vehicle (20% ethanol). The rats were weighed each week. At the end of 12 weeks, urine was to be collected for biochemical assessment therefore the rats were caged individually in plastic cages fitted with steel mesh for a total period of 48 h preceding autopsy and had free access to normal chow diet and water for the first 24 h initially for of acclimatization and then during the next 24 h, animals received only water ad libitum. After twenty-four hours of fasting urine samples were collected in fresh containers, centrifuged at 2000 rpm at room temperature and stored at −20° C. until analyzed. Rats were then euthanized. At autopsy, blood samples were collected by cardiac puncture in tubes, and serum samples collected and frozen until analysis. Uteri were carefully excised, gently blotted, weighed, and fixed for histology and histomorphometry. About 5 mm pieces from the middle segment of each uterus were dehydrated in ascending grades of ethanol, cleared in xylene, and embedded in paraffin wax using standard procedures. Representative transverse sections (5 μm) were stained with H&amp;E stain. Photomicrographs of sections were obtained using a Leica DC 300 camera and Leica IM50 Image Acquisition software fitted to a Leica DMLB microscope. Histomorphometric measurements were done using Leica Qwin-Semiautomatic image Analysis software. μCT (both 2-D and 3-D) determination of excised bones was carried out using the Sky Scan 1076 μCT scanner (Aartselaar, Belgium) using the cone-beam reconstruction software version 2.6 based on the Feldkamp algorithm (Skyscan). The bone marrow was harvested for ex vivo experiments. Both femora were dissected and separated from adjacent tissue, cleaned, and used for RNA isolation and also micro measurements. 
       Evaluation of Trabecular Microarchitecture 
       [0261]    Trabecular response to A-4744/F004 treatment of OVx rats was quantified at the femur epiphysis and tibial proximal metaphysis. Femoral data show (table below) that compared with the sham group, the OVx+vehicle group had reduced BV/TV, Tb.No and Tb.Th, and increased Tb.sp and SMI. Comparison of the A-4744/F004 treatment group with the OVx+vehicle group revealed significant increase in BV/TV and Tb.Th., and decrease in Tb.sp and SMI, suggesting that the microarchitectural features of the femoral trabecular bones are significantly protected by A-4744/F004 treatment of OVx rats.

         [0262]    Tibial trabecular data (table below) show that compared with the sham group, the OVx+vehicle group had significantly reduced BV/TV and Tb.No, and increased Tb.sp and SMI. Comparison of the A-4744/F004 treatment group with the OVx+vehicle group revealed significant increase in BV/TV and Tb.Th., and decrease in Tb.sp and SMI, suggesting that the microarchitectural features of the tibial trabecular bones are significantly protected by A-4744/F004 treatment of OVx rats.

       Evaluation of Estrogen Agonistic Effect 
       [0263]    Estogenicity of the compound A-4744/F004 was evaluated in female Sprague Dawley rats. Figure represents the comparative data of the uterine weight of various groups including OVx and sham. It was observed that rats treated with the extract/compound had no estrogenic effect as uterine weights were comparable to OVx+vehicle group (see  FIG. 2 ). 
       Measurement of Biochemical Parameters 
       [0264]      FIG. 3  shows that serum osteocalcin (assayed for more reliable mid portion of osteocalcin) and urinary CTX levels are elevated in OVx+vehicle group compared with sham+vehicle group. Treatment of A-4744/F004 for 12 weeks to OVx rats resulted in significant reduction in the levels of both these bone turnover markers compared with OVx+vehicle group. These data suggest that A-4744/F004 inhibits bone turnover rate that is characteristically elevated under estrogen deficiency. 
       Ex-Vivo Culture of Bone Marrow Cells (BMCs) 
       [0265]    Bone marrow cells (BMCs) from female Sprague Dawley rats weighing ˜100-180 were isolated at the end of the treatment (12 weeks) and cultures prepared according to a previously published protocol (Maniatopoulos et al., 1988). Briefly, the femora were excised aseptically, cleaned of soft tissues, and washed 3 times, 15 min each, in a culture medium containing 10 times the usual concentration of antibiotics as mentioned above. The epiphyses of femora were cut and the marrow flushed out in 20 ml of culture medium consisting of a-MEM, supplemented with 15% fetal bovine serum, 10 −7  M dexamethasone, 50 μg/ml ascorbic acid, and 10 mM β-glycerophosphate. Released BMCs were collected and plated (2×10 6  cells/well of 12-well plate for mineralization assay and 10 6  cells/well of 48-well plate for ALP assay) in the culture medium, consisting of a-MEM, supplemented with 15% fetal bovine serum, 10 −7 M dexamethazone, 50 μg/ml ascorbic acid and 10 mM β-glycerophosphate. BMCs were cultured from the animals that were given treatment or otherwise for 11 days for ALP production and 21 days for mineralization, and the medium was changed every 48 h. After 21 days, the attached cells were fixed in 4% formaldehyde for 20 min at room temperature and rinsed once in PBS. After fixation, the specimens were processed for staining with 40 mM Alizarin Red-S, which stains areas rich in nascent calcium. Determination of ALP activity by osteoblast cells was done after 11 days of culture. Data show that A-4744/F004 treatment enhanced ALP production and mineralization by BMCs when compared with either OVx+vehicle or sham+vehicle groups (please see  FIG. 4 ). 
         [0000]    Dynamic Histomorphometry after Treatment with A-4744/F004 
         [0266]    New bone formation during the period of administration of A-4744/F004 was assessed by double fluorochrome (tetracycline &amp; calcein) labeling (representative photomicrograph below).  FIG. 5  shows that there was no statistically significant change in mineral apposition rate (MAR) and bone formation rate (BFR) between OVx+vehicle, sham+vehicle groups in the femurs. On the other hand, treatment of OVx rats with A-4744/F004 resulted in significant increase in both MAR and BFR compared with other two groups. 
       Primary Osteoblast Cultures 
       [0267]    Neonatal rat calvarial cell cultures are prepared as described previously (Chattopadhyay et al., Endocrinology 145:3451-62, 2004) using slight modification. Briefly, for calvarial osteoblast cultures, frontal and parietal bones from neonatal Sprague-Dawley rats (1-3 day old) were digested in 0.1% collagenase/0.1% dispase in α-MEM to obtain 5 sequential digests. The second through fifth digests are combined and grown to confluence at 37° C. and 5% CO 2  in air in a-MEM, supplemented with 10% fetal bovine serum (FBS), 2 mM glutamine, 100 U/ml penicillin-streptomycin, non-essential amino acid solution and sodium pyruvate. These osteoblast cells were further used to test thirteen pure compounds designated as 1-13. During the course of culture, pre-osteoblasts undergo three characteristic stages of osteoblasts with the expression of stage specific genes. These are:
       Proliferation &amp; differentiation: Days 1-12
           Genes—cbfa1, Osterix, Alkaline phosphatase,   Collagen-1   
           Extra-cellular matrix maturation: Days 12-18
           Genes—Osteocalcin, Osteopontin, Fibronectin   
           Mineralization: Days 14-35
           Feature—Calcification (nodule formation)   
               
 
       Measurement of Osteoblast Alkaline Phosphatase (ALP) Activity 
       [0275]    Calvarial osteoblasts cells were plated (1500 cells/well in 12 well plate) in the osteoblast differentiation medium and the culture was continued for 10 days with or without treatment with these compounds. This is the time when the ALP levels peak, and serves as an osteoblast differentiation marker. The cells at this point were washed twice with PBS and then plates were fixed by keeping them at −70° C. for 1 h, and then brought to room temperature to determine ALP activity. The rate of the reaction here is directly proportional to the enzyme activity, which itself is proportional to osteoblast differentiation. The O.D. was measured at 405 nm with a microplate reader. Out of all the compounds 1, 3, 4, 6 and 10 showed significantly increased ALP activity ( FIG. 6 ). 
       Comparative In Vivo Osteogenic Efficacy Between Compound 4 and Compound 10 
       [0276]    Ten 1- to 2-day-old rats were divided into two equal groups and given subcutaneous injection of either compound 4 or 10 (each 5.0 mg·kg −1 ·day −1  dose in 50 μl or equal volume of vehicle (normal saline, control) for 3 consecutive days. At the end of the treatment, pups were euthanized, individual calvaria harvested and cleaned of adherent tissue materials by gentle scrapping. Total RNA was isolated and qPCR for BMP-2 performed. 
         [0277]    For the comparison of osteogenic activity of the new compound 10, with compound 4, we studied the effect of compound 10 on the relative expression of the osteogenic gene, bone morphogenetic protein (BMP-2) in primary calvarial osteoblast cells by qPCR. The transcript levels of BMP-2 were significantly increased after treatment with both the compounds (p&lt;0.001). Whereas compound 4 showed 5-fold increase in BMP-2 expression, compound 10 induced it by 15-folds. The results are expressed as fold change over untreated cells ( FIG. 7 ). 
       Bioactive Compounds do not Cause Cell Growth Arrest 
       [0278]    The ability of osteoblasts to replicate in the presence of the compounds (1, 3, 4, 6 and 10) is indicative of safety. Many isoflavonoids at micromolar concentrations are known to inhibit osteoblast cell growth. Osteoblasts were cultured in the absence or presence of compounds (dissolved in 0.01% DMSO final concentration) at various concentrations (1 pM to 1 μM) for 48 h. Cells receiving vehicle (0.01% DMSO) served as control. After incubation, the cells were washed with PBS. Then, cells were treated with MTT solution (5 mg/10 mL in DMEM devoid of Phenol Red) for 4 h. Formazon crystals formed were dissolved in DMSO and O.D. was taken at 540 nm. All the compounds were not toxic to the cells when compared to the control group, and they showed proliferation of the osteoblastic cells at some concentrations ( FIG. 8 ). 
         [0000]    In Vivo Treatment with Compound 10 the Active Constituent from A-4744/F004 of  Dalbergia Sissoo  in Ovariectomized Balb/c Mice 
         [0279]    The study was conducted in accordance with current legislation on animal experiments [Institutional Animal Ethical Committee (IAEC)] at C.D.R.I. Balb/c mice weighing ˜25-30 gm were either bilaterally ovariectomized (OVx) or exposed to a sham surgical procedure. After ovariectomy, mice were left for 30 days for osteopenia to develop. Mice were individually housed at 21° C., in 12-h light:12-h dark cycles. All mice had excess to normal chow diet and water ad libitum. After 8 weeks, treatment in the form of gavage (1.0 mg and 5.0 mg/kg body weight) was given daily. Equal numbers of OVx and sham operated mice served as the control, and were given vehicle. At the end of 8 weeks, mice were euthanized. At autopsy, both femur and tibia were dissected and separated from adjacent tissue, cleaned, and used for μCT measurements. 
         [0280]    As shown in the table below, OVx+vehicle group had significant microarchitectural deteriorations in the femur epiphysis as indicated by reduced BV/TV, Tb.Th and Tb.N compared with the sham group. Compound 10 treatment to OVx mice resulted in increased BV/TV, Tb.Th and Tb.N compared with OVx+vehicle group. Tb.sp and SMI were increased in OVx+vehicle group compared with sham, and compound 10 treatment to OVx mice increased both parameters compared to OVx+vehicle mice.

       Advantages of the Present Invention 
       [0000]    
       
         
           
             A-4744/F004 has bone anabolic (i.e. new bone formation) effect rather than anti-resorptive (stopping further bone loss) effect of the majority of the anti-osteoporotic agents. 
             Unlike raloxifene, an agent of the present invention is devoid of uterine estrogenicity, which is an important safety parameter. 
             All the compounds exhibited no cytotoxicity on osteoblast cells as cell viability was comparable to the control cells (cells receiving vehicle).
