白英中的倍半萜类化合物
采用硅胶柱色谱、Sephadex LH-20柱色谱及制备薄层等方法对白英中的倍半萜进行分离纯化,根据理化性质和波谱数据鉴定其化学结构,发现并鉴定了10个倍半萜,分别为1β-羟基-1,2-二氢-α-山道年(1),boscialin(2),布卢门醇C(3),3β-hydroxy-5α,6α-epoxy-7-megastigmen-9-one(4),去氢催吐萝芙木醇(5),布卢门醇A(6),(1'S,2R,5S,10R)-2-(1',2'-dihydroxy-1 '-methylethyl)-6,10-dimethylspiro[4,5] dec-6-en-8-one (7),(1'R,2R,5S,10R)-2-(1’,2'-dihydroxy-1 '-methylethyl)-6,10-dimethylspiro[4,5] dec-6-en-8-one (8),2-(1',2'-dihydroxy-1 '-methylethyl)-6,10-dimethyl-9-hydroxyspiro[4,5] dec-6-en-8-one(9),蚱蜢酮(10). 10个倍半萜均为首次从白英中发现.
