DM was induced in rats with streptozotocin (STZ); then, five different treatments were applied, including group I (untreated healthy control), group II (diabetic and untreated), group III (diabetic and treated with metformin), group IVI (diabetic and treated with glipizide), and group V (diabetic and treated with a combination of metformin and glipizide. Lipid peroxidation (LPO), nitric oxide (NO), total antioxidant capacity (TAC), fasting blood glucose (FBG), glycated hemoglobin (HbA1c), total cholesterol, triglycerides, high-density lipoprotein (HDL), low-density lipoprotein (LDL), creatinine, and urea were measured. The authors observed that the therapeutic benefits of metformin and glipizide are complementary. Metformin exhibited superior performance in improving glycemic control and decreasing oxidative stress, whereas glipizide was more effective against dyslipidemia. This information could be helpful for the future treatment of vascular patients, antilipidemic medicines, and antioxidant therapy to improve the quality of life. Plants of the genus _Thymus_ L. are traditionally used in medicine and cooking due to the presence of biologically active compounds in them that exhibit fungicidal, antibacterial and other medicinal properties and original taste qualities. However, information on the contents and distributions of elements in the organs of _Thymus_ L. is limited. The study of [PERSON] et al. [15] was to set and compare the elements in organs of wild thyme for different soil and climatic conditions. Two species of wild _Thymus_ L. from the Mongolian steppe and on the coast of Lake Baikal were collected during flowering. Twenty-four elements, including Si, in soils, roots, stems, leaves, and flowers were simultaneously determined by atomic emission spectrometry. Elemental profiles of two species of wild _Thymus_ L. are described. It is assumed that Si is a necessary element of the plant. The predominance of the genetic resistance of plants over the influence of soil and climatic conditions is shown. The novelty of study of [PERSON] and [PERSON] [16] was the comparison between fresh and dried forms of herbs and spices and additionally between dried in a freeze-drying process and commercially available (in dried forms). The content of total polyphenols (TP) and the antioxidant activity (AA) of fresh herbs (13 in total) and those subjected to the freeze-drying process (stems and leaves separately) were compared. Moreover, the content of TP and AA of commercial food spices (19 in total) of the two leading companies on the Polish market were compared. It was found that fresh herbs and spices exhibited a large accumulation of polyphenolic compounds (from 466.55 to 17.23 CAE/100 g, for lemon balm and ginger, respectively). For freeze-dried herbs and spices, the highest TP content was found for marjoram (3052.34 CAE/100 g--leaves). Among commercial herbs and spices, sage (971.28 CAE/100 g) deserves attention. Fresh herbal spices, particularly oregano, (236.21 \(\upmu\)M TE/g), had the highest AA. The AA of freeze-dried herbs and spices was much lower (5.27-1.20 \(\upmu\)M TE/g). The average value obtained for commercially available herbs and spices was 1.44 \(\upmu\)M TE/g. In the case of AA measured by the DPPH radical, thyme was characterized by the highest activity among fresh marjoram for freeze-dried herbs and spices. For dried commercial spices, the highest levels of AA were found for cumin. Pumpkin flowers, in their composition, contain many bioactive ingredients that have a beneficial effect on the human body. The aim of the study by [PERSON] et al. [17] was to evaluate the antioxidant activity and chemical composition of flowers of various species and varieties of pumpkins: Amazonka, Ambar, Atlantic Giant, Bambino (_Cucurbita maxima_ L.), Butternut, Muscade de Provence, Rouge vif d'Etampes (_Cucurbita mosclata_ Duch. ), and Miranda (_Cucurbia pepo_ L.). The total polyphenols, carotenoids, total sugar contents, antioxidant activity, and fatty acid composition were determined.
