Abstract
From the fronds of Wagneriopteris formosa Loeve et Loeve a new flavonol glycoside, quercetin-3-O-.beta.-D-alloside, was isolated along with kaempferol-3-O-.beta.-D-alloside. From the fronds of Woodsia polystichoides Eaton a new flavonol acylglycoside kaempferol-3-O-.alpha.-L-(3''''-O-acetyl) arabinofuranoside-7-O-.alpha.-L-rhamnopyranoside and its deacetylglycoside were isolated. Their structures were determined by chemical and spectroscopic methods.Keywords
