Abstract
A quercetin glycoside has been isolated from Kalanchoe prolifera. Its structure has been established as quercetin-3-O-beta-D-glucopyranosyl- (1 --> 2)-beta-D-xylopyranoside on the basis of its synthesis starting either from 1,2-O-isopropylidene-alpha-D-xylofuranose or from 1,3,4-t ri-O-acetyl-alpha-D-xylopyranose.
