The study of volatile fractions of Cabbage leaves (Brassica oleracea L. convar. capitata (L.) Alef. var. alba DC.) and determination of its antibacterial and antifungal activity:(TJPS-2020-0151)

Along with a widespread application of cabbage as a food and fodder crop it also possesses therapeutic properties. In traditional medicine this plant is used in gastritis and gastric ulcer, colitis, diabetes, inflammations of upper airways, musculoskeletal system, disorders of cardiovascular system and skin. Using the method of gas chromatography the component composition of cabbage leaves of Yaroslavna and Bilosnizhka cultivars was studied. Testing control strains of microorganisms were used for determination of the antimicrobial activity of chloroform, ethyl acetate and 96% ethanol extracts from cabbage cultivars leaves. The general amount of volatile compounds in the studied plant material types was almost equal. Allyl isothiocyanate, dihydropseudoionone, and ar-turmerone were chosen as marker compounds for cabbage leaves of Yaroslavna cultivar, while nerolidol and 3,5-di-tret-butyl-4-hydroxybenzaldehyde were chosen for cabbage leaves of Bilosnizhka cultivar. Testing control strains of Esсherichia coli, Pseudomonas aeruginosa, Proteus vulgaris and. Candida albicans were sensitive to all tested extracts from cabbage leaves of Yaroslavna and Bilosnizhka cultivars. The results provide the reason for the development of new antibacterial drugs based on cabbage leaves. :TJPS-2020-0151
