Abstract

A new flavonol glycoside named myricetin-3-O-(5''-acetyl αarabinofuranoside) has been isolated from Polygonum bellardii All. F. Polygonaceae growing in Egypt, together with quercetin-3O-(5''-acetyl α-arabinofuranoside), quercetin-3-O-rutinoside (rutin), α-amyrin, β-sitosterol and β-sitosterol-3-O-β-glucoside. Their structures were elucidated using different spectral techniques.
