箭叶淫羊藿化学成分研究

Studies on the Chemical Constituents of Sagittate Epimedium (Epimedium sagittatum)

从箭叶淫羊藿Epimediumsagittafum中分到了3个化合物：β－谷甾醇，β－谷甾醇葡萄糖试及一新黄酮化合物──箭叶素。经波谱分析和化学反应测定其结构为5－羟基－6，7－二甲氧基－3＇，4＇－亚甲二氧基黄酮。

From Epimedium sagittatum Maxim, thre. compounds Were isolated. They are β-sitostcrol, β-sitosterolglucoside a nd a new flavone compound I. Ry spectroscopic and cnemical mcthods, I was elucidated as 5-hydroxy-6, 7-dimethoxy-3＇, 4＇-methylene-dioxyflavone.
