Flavonoid glycosides in nine Polygonum L. taxons

Abstract

Eighteen flavonoid glycosides were identified in the following taxons of the Polygonum L. genus: P. hydropiper L., P. bistorta L., P. aviculare L., P. persicaria L., P. lapathifolium ssp. tomentosum (Schrank) Dans, P. lapathifolium ssp. nodosum (Pers.) Dans, P. amphibium L., P. mite Schrank, P. convolvulus L. (Bilderdykia convolvulus L.). The content of fourteen flavonoid glycosides was determined. Reversed Phase High Performance Liquid Chromatography was applied for separation, identification and quantitative determination of these compounds.
