Dynamics of content and flavonoid component composition in Polygonum aviculare L

摘要

Uglanin (kaempferol-3-O-arabinoside) is the main flavonol glycoside in P. aviculare (aerial parts) throughout the vegetation period. Flavonoid content was studied as percentage composition (concentration) and in mg/plant (absolute DW) at different stages of development. Three principal glycosides of P. aviculare, uglanin, hyperoside (quercetin-3-O-galactoside) and an unidentified flavonol glycoside, are the stable chemical characters suitable for intraspecific chemotaxonomy of this complex species.
