Acylated flavonol glycosides from Sedum aizoon

A new acylated flavonol glycoside (1) and a known compound (2) have been isolated from the whole plant of Sedum aizoon L. Their structures have been established as quercetin 3-O-[β-D-(2‴-O-(E)-feruloyl)-xylopyranosyl]-(1 → 6)-β-D-glucopyranoside (1) and rutin (2) by means of spectroscopic analysis and chemical methods.
