[摘要]
从豆科植物大果油麻藤Mucuna macrocarpa的藤茎中分得7个成分,通过化学反应,mp,IR,MS,1H及13CNMR(DEPT)等分别鉴定为羽扇烯酮(lupenone,Ⅰ)、无羁萜(friedelin,Ⅱ)、β-谷甾醇、△5,22-豆甾烯酸(△5,22-stigmasten-3β-ol,Ⅳ)、二十四烷酸α-单甘油酯(tetracosanoic acid2,3-dihydroxypropyl ester,Ⅴ)、二十五烷酸α-单甘油酯(pentacosanoic acid2,3-dihydroxypropyl ester,Ⅳ)、二十六烷酸α-单甘油酯(hexacosanoic acid2,3-dihydroxpropyl ester,Ⅶ)、其中Ⅵ为一新化合物,而Ⅵ和Ⅶ作为天然产物首次从植物中分得。
