The paper presents new data on chemical composition and antioxidant properties in extracts of the aerial organs of Saponaria officinalis growing on the territory of the Republic of Buryatia. It was revealed that soapberry leaves extracts contain a number of organic acids such as oxalic, formic, fumaric, succinic, malic, citric, and benzoic ones, the dominant being formic, malic, acetic and citric acids. Of vitamins B2, B3. BC extracted from the plant the dominant one was riboflavin. The method of and Fthigh-performance liquid chromatography helped to reveal five compounds identified as aglycone and glycosidic in character. They are orientin, isoeryentin, isovitinexin-7-О-glycoside, orientin-7-О-glycoside, of which isovitoxin is dominant. The greatest total antioxidant activity was demonstrated by soapberry leaves and inflorescences picked up on abandoned sites of the village of Selenginsk. Extractions from Saponaria officinalis leaves showed showed antiradical and Fe2+-chelating activity comparable to that of the extractions from plants with pronounced antioxidant activity. Thus, the data obtained indicated the antioxidant activity of S.officinalis aqueous extracts due to the presence of natural flavonoids. This fact shows the plant as a promising new source of antioxidants.

Green and red tea due to the strong antioxidant, anti-inflammatory, anti-microbial, anti-tumor features are an intensive object of research. This article explores the chemical composition and biological activity of green and red tea of different fermentation. The preparation of aqueous extracts was implemented in household conditions, and the extraction time of release of active compounds from raw material was evaluated. The antibacterial activity was evaluated by the method in vitro. The research has shown that green tea is rich in catechins and caffeine. Red tea provides rutin and gallic acid. Green tea extracts inhibited the growth of S. aureus ir B. cereus. On the basis of the research results on the antioxidant activity, teas can be arranged in the following sequence: green > white > Oolong > red.

High Antioxidant Activity

Hydro-distillated essential oils (EO) antioxidant activity of three endemic medicinal plants of Iran namely, Heracleum lasiopetalum Boiss., Kelussia odoratissima Mozaff., and Ferulago angulata (Schlecht.) Boiss were studied. The results indicated that the major components of the EOs were 2-ethylhexyl acetate (34.5%), n-octanol (6.5%), and hexanol (5.1%) for H. lasiopetalum fruits; Z-?-ocimene (20.5), ?-pinene (11.6%), and ?-phellandrene (9.3) for F. angulata aerial parts; ?-pinene (20.1%), 1,8-cineole (18.2%), and Zligustilide (15.5%) for K. odoratissima aerial parts. The three EOs having high antioxidant activity could be used as an alternative preservative instead of synthetic ones in food industry. DOI: http://dx.doi.org/10.3329/bjb.v42i2.18038 Bangladesh J.
