摘要: 以喜树叶为原料,用0.3%NaOH碱法提取,加入生石灰过滤去除果胶,用乙醇萃取滤液,然后用盐酸调pH=3。经柱层析用梯度淋洗法可分别得到喜树碱和10-羟基喜树碱,淋洗条件为:2%甲醇的氯仿溶液和4%甲醇的氯仿溶液。喜树碱的收率为0.34‰,羟基喜树碱的收率为0.02‰。喜树碱和羟基喜树碱的纯度均在98.5%以上。

Abstract: The leaves of camptotheca acuminate decne are used as the raw material for extraction of camptothecin and 10-hydroxycamptothecin.The leaves are dipped in 0.3% NaOH.Quicklime is added to precipitate the pectin and filtrate it.The liquid is extracted by ethyl alcohol.Then the filtrate liquid is become pH=3 though dropping in hydrochloric acid.The camptothecin and 10-hydroxycamptothecin can be gotten by the 2% and 4% methanol in the chloroform through the silica chromatogram.The rate of yield of camptothecin and 10-hydroxycamptothecin is 0.34‰ and 0.02‰ respectively,and their purity all exceed 98 %(HPLC).

Key words: leaves of camptotheca acuminate decne, Camptothecin, 10-Hydroxycamptothecin, separating
