摘　　要：目的:研究睡莲科芡属植物芡Euryale ferox Salisb.的成熟种仁芡实的化学成分。方法:对芡实95%乙醇提取物的石油醚和乙酸乙酯部位采用硅胶柱色谱、Sephadex LH-20柱色谱等方法分离纯化;根据理化性质和波谱数据鉴定化合物结构。结果:从芡实中分离并鉴定了7个化合物,分别为:原儿茶酸(1)、没食子酸(2)、没食子酸乙酯(3)、5,7-二羟基色原酮(4)、β-谷甾醇(5)、胡萝卜苷(6)、5,7-二羟基-6,4'-二甲氧基黄酮(7)。结论:以上化合物均为首次从该植物中分离得到。Objective： To study the chemical constituents from the seeds of Euryale ferox. Methods： The chemical constituents were isolated by silica gel column,Sephadex LH-20 and their structures were identified by physico-chemical and spectral analysis. Results：Seven compounds were purified from the 95% ethanol extract. These constituents were elucidated as protocatechuic acid（ 1）,gallic acid（ 2）,gallic acid ethyl ester（ 3）,5,7-dihydroxychromone（ 4）,β-sitosterol（ 5）,daucosterol（ 6）,and 5,7-dihydroxy-6,4＇-dimethoxyflavone（ 7）,respectively. Conclusion： All compounds are isolated from this plant for the first time.
