IDENTIFICATION OF THE PHENOL COMPOUNDS IN THE ROOTS OF HELIANTHUS ANNUUS L. (ASTERACEAE)

Abstract

Using high-performance liquid chromatography we have found that the roots of Helianthus annuus L. (Asteraceae), gathered during the blooming period in Predgorny District of Stavropol Krai, contain 13 phenol compounds, and during the phase of seed ripening (after sunflower harvesting) the roots contain 10 phenol compounds, among which there is a group of oxycinnamic acids and their derivatives (chlorogenic, neochlorogenic, caffeic and ferulic acids) as well as flavonoids (rutin, hyperoside, luteolin-7-glycoside, apigenin, dihydroquercetinum, naringenin), coumarin and high-molecular polyphenol compounds (tannin, gallic and ellagic acids, epicatechin, epigalocatechin gallate).
