ABSTRACT
Two new flavonol glycosides, fissmacosides A (1) and B (2) along with two known flavonol glycosides, kaempferol 3-O-α-l-rhamnopyranosyl-(1â6)-ß-d-galactopyranoside (3) and kaempferol 3-O-ß-d-glucopyranosyl-(1â4)-α-l-rhamnopyranosyl-(1â6)-[4-(E)-feruloyl]-ß-d-galactopyranoside (4) were isolated from the methanol extract of the leaves of Fissistigma maclurei Merr. Their structures were determined on the basis of extensive spectroscopic methods, including 1D-, 2D-NMR, and MS data.
