一种提纯粗茶皂素的简易方法

A simple method for purification of crude tea saponin

对粗茶皂素的提取纯化工艺进行了研究。以质量分数为70%的粗茶皂素为原料,经2%NaOH溶解、盐酸酸析、95%乙醇溶解、丙酮沉析工艺得到精制茶皂素。检测结果表明,茶皂素质量分数大于95%,提取率大于80%,这种简便易行的工艺得到的茶皂素可作为开发新型植物灭螺剂的原料。

A simple purification method for crude tea saponin was described. The 70% of crude tea saponin was dissolved in 2% sodium hydroxide aqueous solution and precipitated by adding 20% hydrochloric acid. The deposit was dissolved with 95% ethanol, and the acetone was added to the ethanol solution to make the tea saponin to be precipitated. The yield of purified tea saponin was more than 80% with the purity of 95%.
