Abstract

Five flavonoids were isolated from Hedyotis diffusa Willd. Their structures were elucidated as kaempferol (I), kaempferol 3-O-beta-D-glucopyranoside (II), kaempferol 3-O-(6"-O--L-rhamnosyl)-beta-D-glucopyranoside (III), quercetin 3-O-beta-D-glucopyranoside (IV) and quercetin 3-O-(2"-O-beta-D-glucopyranosyl)-beta-D-glucopyranoside (V) by spectroscopic analysis. Compounds I - III and V were originally isolated from H. diffusa.

摘要

从白花蛇舌草中分离出了五种黄酮类化合物。通过光谱分析确定它们的结构分别为山柰酚（I）、山柰酚3 - O - β - D - 吡喃葡萄糖苷（II）、山柰酚3 - O -（6″ - O - α - L - 鼠李糖基）- β - D - 吡喃葡萄糖苷（III）、槲皮素3 - O - β - D - 吡喃葡萄糖苷（IV）和槲皮素3 - O -（2″ - O - β - D - 吡喃葡萄糖基）- β - D - 吡喃葡萄糖苷（V）。化合物I - III和V最初是从白花蛇舌草中分离得到的。
