Medicinal plants: Filimarin, a new flavanol glycoside from filipendula ulmaria and its antioxidant activity
Pharmaceutical Chemistry Journal(2010)
Abstract
A new quercetin glycoside named filimarin was isolated from honeysweet (Filipendula ulmaria L. Maxim.) by colun chromatography over polyamide and silica gel. Based on chemical and spectral data, the structure of filimarin is identified as quercetin-4'-O-beta-D-galactopyranoside. Results of voltammetric measurements showed that filimarin possesses pronounced antioxidant activity that is comparable with that of dihydroquercetin and ascorbic acid.
