| 摘 要： | 以乙酸乙酯为溶剂对狼毒大戟干燥根粉进行超声提取,依次用石油醚、乙酸乙酯、甲醇进行萃取,将乙酸乙酯萃取物真空浓缩后用硅胶柱色谱分高,以石油醚、乙醚、氯仿、乙酸乙酯等不同溶剂洗脱,从中分离得到4个二帖类化合物,经化学和波谱学方法鉴定分别为4,4,10,17-四甲基-8,11,14-三羟基α、β不饱和内酯(Ⅰ)；JolkinolideA (Ⅱ)；JolkinolideB(Ⅲ),β-香树脂醇乙酸酯(β- amyrin acetate)(Ⅳ).其中化合物Ⅰ为首次从该植物中分离得到. |
| 关 键 词： | 狼毒大戟 乙酸乙酯提取物 不饱和内酯 |

| Abstract: | Ethyl acetate-extract of Euphorbia fischeriana was obtained by means of ethyl acetate extraction,and then extracted by various solvents in turn,such as ethylether,ethyl acetate and methanol,etc.The ethylether fraction was concentrated in vacuo to give a residue,which was subjected to silica gelcolumnchromatography,eluted with petroleum ether,ethyl ether,chloroform,ethyl acetate and their mixtures.Four compounds were isolated.By using MS,IR and NMR analysis,the compounds were identified as 4,4,10,17-tetramethoxy-8,11,14-trihydroxy-α,β terpenes(Ⅰ),Jolkinolide A(Ⅱ),Jolkinolide B(Ⅲ),β-amyrin acetate(Ⅳ),respectively.Among them,compoundⅠ is firstly isolated from Euphorbia fischeriana. |
| Keywords: | Euphorbia fischeriana ethyl acetate-extract unsaturated lactone |
