Two new acylated flavonol glycosides from the seeds of Lepidium sativum.
Two new acylated flavonol glycosides named kaempferol-3-O-(2-O-sinapoyl)-β-D-galactopyranosyl-(1 → 2)-β-D-glucopyranoside-7-O-α-L-rhamnopyranoside (1) and quercetin-3-O-(6-O-benzoyl)-β-D-glucopyranosyl-(1 → 3)-β-D-galactopyranoside-7-O-α-L-rhamnopyranoside (2), were isolated together with six known compounds from the seeds of L. sativum. Their structures were elucidated on the basis of spectros...
