西南金丝梅的黄酮成分研究

FLAVONOIDS FROM HYPERICUM HENRYI LEVL. ET WAN.

从西南金丝梅(hypericum henryi)的地上部分分得6个黄酮类化合物,应用光谱分析和化学方法鉴定其结构为二氢槲皮素,(2R,3R)二氢槲皮素-3-O-α-L-鼠李糖甙,二氢槲皮素-7-O-α-L-双鼠李糖甙,槲皮素,槲皮素-3-O-α-L-鼠李糖甙和槲皮素-7-O-α-L-鼠李糖甙。

From the leaves and stems of Hypermim henryi,six flavonoids,dihydroquercetin, (2R. 3R) dihydroquercetin-3-O-α-L-rhamnoside, dihydroquercetin-7-O-α-L-rhamnoside, quercetin , quercetin 3-O-α-L-rhamnoside and quercetin-7-O-α-L-rhamnoside were isolated. Their structures were deduced from spectroscopic and chemical evidences.
