RESEARCH OF PHENOLIC COMPLEX OF LEAVES OF MESPILUS GERMANICA L. by N. N. Vdovenko-Martynova

“…Qualitative composition and quantitative identification of phenolic compounds in the air-dry raw materials of samples under study was done using qualitative reactions and high performance liquid chromatography method (HPLC). 13 compounds were received, 8 of them were identified as the substances of phenolic origin: flavonoids (quercetine, taxofolin, luteolin), hydroxycoric acids (gallic, chlorogenic, ferulic), polyphenolic compounds (epigallocatechin gallate, epicatechin). The sum of identified phenolic compounds amounted to 78,24% of all compounds found by the given method.…”
