| 摘 要： | 将杠柳枝皮粉末的乙醇提取物悬浮于水后,依次用石油醚、乙酸乙酯和正丁醇萃取.对乙酸乙酯萃取物采用各种柱层析进行多次分离后得到4个化合物,经波谱分析,鉴定它们的结构分别为β-香树素乙酸酯(1)、β-香树素(2)、periplogenin(3)和perilocoside N(4),其中化合物1和2是首次从该植物中分离得到. |

| Abstract: | The ethanol extract from the twig bark powder of Periploca sepium was suspended in water and successively treated with petroleum ether,ethyl acetate and n-butanol.The ethyl acetate fraction was repeatedly separated on silica gel column and Sephadex LH-20 column to give the four compounds.The structures of four compounds were elucidated as β-amyrin acetate(1),β-amyrin (2),periplogenin(3) and perilocoside N(4)by combined spectral analysis.Among them,compounds 1 and 2 were found for the first time in the plant. |
