Various physicochemical methods of analysis are used for evaluation of plant antioxidant activity. Composition of ethanol extracts of red, yellow and white onion husks, dried rosemary, basil, and chaga were studied by high performance thin layer chromatography (HPTLC) method. The antioxidant activity of the obtained fractions on a chromatographic plate was assessed by subsequent DPPH screening. The extracts red and yellow onion husk and rosemary demonstrated the highest antioxidant activity, variability of the qualitative composition and similarity of antioxidant profiles, while extract of white onion husks did not contain any antioxidant classes. Intensive spots with Rf of 0.13-0.97 were observed along the whole chromatogram track corresponding to red onion husks. It was also found that all tested extract, excepting white onion husk and chaga, contained spots with varying degrees of intensity in the Rf range of 0.96-0.98, which corresponded quercetin Rf value.</p></abstract><trans-abstract xml:lang="ru"><p>Для исследования антиоксидантной активности растительного сырья, которое является богатым источником эффективных нетоксичных биологически активных веществ, используются различные физикохимические методы анализа. В данной работе был применен метод высокоэффективной тонкослойной хроматографии (ВЭТСХ) для разделения биологически активных веществ, входящих в этанольные экстракты шелухи красного, желтого и белого лука, сушенных розмарина, базилика и чаги. Антиоксидантную активность полученных фракций на хроматографической пластине оценивали последующим DPPH-скринингом. Наибольшими показателями антиоксидантной активности и вариабельностью качественного состава характеризовались экстракты шелухи красного и желтого лука, а также розмарина, причем для этих образцов была отмечена схожесть антиоксидантных профилей. В экстракте белого лука не было обнаружено каких-либо классов антиоксидантов. Для шелухи красного лука было отменено наличие значительно выраженных пятен по всему треку, значения Rf которых расположены в диапазоне 0,13-0,97. Доказано, что все экстракты, кроме шелухи белого лука и чаги, в разной степени интенсивности имеют пятна с коэффициентом замедления в диапазоне 0,96-0,98, что соответствует полученному значению Rf кверцетина.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>растительные экстракты</kwd><kwd>антиоксидантны</kwd><kwd>коэффициенты замедления</kwd><kwd>фенольные соединения</kwd><kwd>флавоноиды</kwd><kwd>кверцетин</kwd><kwd>высокоэффективная тонкослойная хроматография</kwd></kwd-group><kwd-group xml:lang="en"><kwd>plant extracts</kwd><kwd>antioxidants</kwd><kwd>ratio of front</kwd><kwd>phenolic compounds</kwd><kwd>flavonoids</kwd><kwd>quercetin</kwd><kwd>high performance thin layer chromatography</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Исследования проведены в рамках темы научного исследования № 013.21.05 по государственному заданию ФГБНУ «ФНЦ пищевых систем им.
