The aim of work is studying the chemical composition of phenolic compounds (PC) and comparative assessing the quantitative content of flavonoids as the most valuable PC group in different species of fruits. PC composition research was completed applying HPLC method in reverse-phase mode. Different concentrations of ethyl alcohol were employed to extract flavonoids while determining their total content. The extraction was carried out with the use of three methods: method of infusion (1, MI), in an ultrasonic extractor (2, US) and under the influence of super high frequencies electromagnetic field (3, SHF). Species differences were assessed on UV spectra of the colored complexes of PC extracts with aluminum chloride. 13 PC components content was quantified for fruits collected in 2014-2016. Dominating components were revealed: they are chlorogenic acid and hyperoside. Species of barberry with the most valuable PC sets were determined: Dark purple barberry (Berberis vulgaris f. atropurpurea Regel), Thunberg barberry (Berberis thunbergii DC) – samples of 2015 year of collection, Regel barberry (Berberis regeliana Kochne) – those of 2016. The total flavonoids (F) content measured by spectrophotometric method (with quercetin as a reference solution) while extracting them by infusion in three species of barberry fruits varies from 1,30 to 1,41 %. While defining the optimum extraction method maximum extent of F extraction from barberry fruits reached 39%, from wild rose fruits – 51,5 % (SHF-extraction). According to the results of the research there are recommendations given on using extracts as substances for producing medical and pharmaceutical herbal remedies and food additives with antioxidant properties.AuthorsN.A.
