大苞蛇根草化学成分的研究

Chemical Studies on Ophiorrhiza grandibracteolata

利用柱色谱技术进行分离纯化,通过理化性质及波谱方法对大苞蛇根草单体化合物进行了结构鉴定。从中共得到6个单体化合物,分别为豆甾醇(1)、β-谷甾醇(2)、胡萝卜甙(3)、3β-乙酸基-20-羽扇豆烷(4)、无羁萜(5)、铁力木酸(6)。均为首次从该植物中得到。

To investigate the chemical constituents of Ophiorrhiza grandibracteolata, the compounds were separated with column chromatography and their chemical structures were identified by physioehemieal and spectral method respeetively. Six compounds were isolated from the plant. They were identified as α-ecdysone （1） ,β-daucosterol （2） , vineosamide （ 3）,3β-acetoxy-20-1upanol （ 4）, friedelin （ 5 ）, myrtifolic acid （ 6 ）. The six compounds were isolated from the plant for the first time.
