Abstract

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-->6)-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.

摘要

对韭菜（葱属植物韭葱）鳞茎提取物进行的植物化学研究，已从山奈酚苷元的基础上分离出五种黄酮苷。其中两种是新化合物，已通过包括二维核磁共振在内的光谱方法鉴定为山奈酚3 - O - [2 - O -（反式 - 3 - 甲氧基 - 4 - 羟基肉桂酰基）-β - D - 吡喃半乳糖基] -（1→4）- O - β - D - 吡喃葡萄糖苷和山奈酚3 - O - [2 - O -（反式 - 3 - 甲氧基 - 4 - 羟基肉桂酰基）-β - D - 吡喃葡萄糖基] -（1→6）- O - β - D - 吡喃葡萄糖苷。已对分离出的化合物进行了人体血小板抗聚集活性评估。
