摘要：

A phytochemical investigation of the extracts obtained from bulbs of leek, Allium porrum L. has led to the isolation of five flavonoid glycosides based on the kaempferol aglycone. Two of them are new compounds and have been identified as kaempferol 3-O-[2-O-(trans-3-methoxy-4-hydroxycinnamoyl)-beta-D-galactopyranosyl]-(1-->4)O-Beta-D-glucopyranoside, and kaempferol 3-O-[2-O-(trans-3-methoxy-4-hydroxycinnamoyl)-beta-D-glucopyranosyl]-(1 -->4)-O-beta-D-glucopyranoside on the basis of spectroscopic methods. including 2D NMR. The isolated compounds have been evaluated for their human platelet anti-aggregation activity. (C) 2001 Elsevier Science Ltd. All rights reserved.
