【摘要】 对川山橙的化学成分进行研究,通过采用硅胶柱、ODS、Sephadex LH-20等柱色谱方法进行分离纯化,根据理化性质与波谱数据鉴定了14个化合物的结构,分别为11-hydroxytabersonine(1)、venalstonidine(2),sandine(3),齐墩果酸(4),熊果酸(5),白桦脂醇(6),(+)松脂醇(7),(-)丁香脂素(8),8-羟基-松脂素(9),(-)-latifolin(10),甲基条叶蓟素(11),马钱素(12),对苯二甲酸二丁酯(13),β-谷甾醇(14),其中化合物4～14为首次从该植物中分离得到。更多还原

【Abstract】 To study the chemical constituents in the twigs and leaves of Melodinus hemsleyanus.The chemical constituents were isolated by silica gel,ODS and Sephadex LH-20 column chromatographies.Their structures were determined by chemical and spectroscopic methods.Fourteen compounds were isolated from the 95%ethanol extract of the twigs and leaves of M.hemsleyanus.Their structures were identified as 11-hydroxytabersonine(1),venalstonid(2),sandine(3),oleanolic acid(4),ursolic acid(5),betulin(6),(+)-pinoresinol(7),(-)-syringaresinol(8),8-hydroxypinoresinol(9),(-)-latifolin(10),cirsilineol(11),loganin(12),dibutylterephthalate(13),and β-sitosterol(14).Compounds 4-14 were obtained from this plant for the first time.更多还原
