四川山姜的化学成分研究

Chemical Components of Alpinia sichuanensis Z.Y.Zhu

摘要: 采用正相硅胶和Sephalex LH-20凝胶色谱柱层析等分离方法对姜科山姜属植物四川山姜的乙酸乙酯部位的成分进行分离纯化,根据理化性质和波谱数据进行结构鉴定。分离得到了8个化合物,分别鉴定为3,5-二羟基-4',7-二甲氧基黄酮(1)、4',7-二羟基-5-甲氧基二氢黄酮(2)、4',5,7-三羟基黄酮(3)、5,7-二羟基-4'-甲氧基黄酮(4)、对香豆酸(5)、β-胡萝卜苷(6)、β-谷甾醇(7)和豆甾醇(8)。化合物1～5为首次从该植物中获得。

Abstract: Chemical constituents of Alpinia sichuanensi were studied.Eight compounds were isolated and purified by Silic Gel and Sephadex LH-20 column chromatography. Their structures were elucidated by chemical and spectroscopic methods as 3, 5-dihydroxy-4',7-dimethoxyflavone(1), 4',7-dihydroxy-5-methoxyflavanone(2), 4',5,7-trihydroxyflavone(3), 5,7-dihydroxy-4'-methoxyflavone (4), p-coumaric acid(5), β-daucosterol(6), β-sitosterol(7), stigmasterol(8).Compounds 1-5 are isolated from this plant for the first time.
