The content and chemical composition of phenolic compounds in above- and underground organs of dropwort during second year of plant vegetation were studied. Five flavonoids (hyperosid, astragalin, spireaoside, kaempferol, quercetin), 2 catechin derivatives ((+)-catechin, (-)-epigallocatechin), and 7 polyphenolic acids (ellagic, gallic, syringic, salicylic, chlorogenic, caffeic and rosmarinic) were identified in aboveground organs. Their content, both in flowers and leaves, was significantly higher at the beginning of flowering as compared with full flowering stage. In underground organs (+)-catechin and its derivatives ((-)-epigallocatechin, (-)-epigallocatechin gallate, (-)-epicatechin) as well as 2 polyphenolic acids (ellagic and gallic) were identified. Their content was not closely related to the stage of plant development.
