摘要: 采用正反相硅胶、Sephadex LH-20和HPLC等色谱手段对绿玉树Euphorbia tirucalli化学成分进行分离纯化,从绿玉树地上部分70%丙酮提取物中分离得到12个化合物。利用MS、1H-NMR和13C-NMR等现代波谱技术确定化合物结构为4α-去氧-巴豆醇-13-乙酸酯(1)、对映-3β,13S-二羟基-26-烯-14-阿替森酮(2)、羊毛甾醇(3)、3表-粘霉烯醇(4)、齐墩果烷-9(11),12-二烯-3-酮(5)、β-香树烯酮(6)、齐墩果烷-18-烯-3-酮(7)、无羁萜(8)、4-豆甾烯-3-酮(9)、β-谷甾醇(10)、山奈酚-3-O-α-L-鼠李糖苷(11)和东莨菪内酯(12)。其中,化合物1、2、5~7、9和12为首次从该植物中分离得到。

Abstract: Twelve compounds including a tigliane diterpene ester,4α-deoxy-phorbol-13-acetate(1),a atisane diterpene, ent-(3β,13S)-dihydroxyatis-16-en-14-one(2),together with six triterpenoids,lanosterol(3),3-epi-glutinol(4),oleana-9(11),12-dien-3-one(5), β-amyrenone(6),olean-18-en-3-one(7),friedelin(8),and four other compounds,stigmast-4-en-3-one(9), β-sitosterol(10),kaempferol 3-O-α-L-rhamnoside(11)and scopoletin(12),were isolated from the 70% acetone extract of Euphorbia tirucalli. Their structures were elucidated by spectroscopic analysis,including 1D NMR,2D NMR and ESI-MS.Among them,compounds 1,2,5-7,9 and 12 were isolated from E.tirucalli for the first time.
