目前世界各国都在致力于寻找薯蓣皂甙元产量高的薯蓣属植物,同时对能够提供薯蓣皂甙元及其类似物的其它植物,也正在进行探索。本文对苦木科植物 B.roxburghii 的叶子和果仁部分作了较系统的研究。研碎的值物果仁(180克)在索氏提取器中以甲醇回流提取,所得稠厚浓缩物经己烷及乙醚浸渍处理后,将其溶于最少量的乙醇中,加入大量乙醚使皂 At present, all countries in the world are devoting themselves to finding the genus Dioscorea with high yield of diosgenin and exploring other plants capable of providing diosgenin and its analogs. This article made a more systematic study of the leaves and kernels of the bitter woody plant B.roxburghii. The ground nut kernels (180 g) were extracted by refluxing with methanol in a Soxhlet extractor. The resulting thick concentrate was impregnated with hexane and diethyl ether, dissolved in the minimum amount of ethanol, and added with a large amount of diethyl ether soap
