摘　　要：巴西甘薯叶[IpomoeabatatasLam .(cv.Simon) ]的氯仿成分经反复硅胶柱层析分离得到了8个化合物,通过理化性质和波谱方法分别鉴定为:乙酰β香树醇( 1)、木栓酮( 2 )、表木栓醇( 3)、三十烷醇( 4 )、β谷甾醇( 5 )、咖啡酸乙酯( 6 )、东莨菪素( 7)和胡萝卜苷( 8)。其中3、4、6。Eight compounds:β-amyrin acetate (1),friedelin (2),epifriedelanol (3),n-triacontanol (4),β-sitosterol(5),ethyl caffeate (6),scopoletin(7)and daucosterol (8) were isolated by silica gel chromatography from the leaves of Ipomoea batatas Lam(cv Simon),and their structures were elucidated on the basis of physico-chemical properties and spectral data.Compound 3,4,6,7 and 8 were obtained from this plant for the first time.
