茶皂素提取与纯化的工艺探讨

Study on the extraction and purification of the theasopoin

首先从定量上分析茶皂素在浓缩过程中的分解温度,然后用有机溶剂乙醇来提取茶枯饼中的茶皂素,并且寻找最佳的浓缩温度和真空度,最后通过实验确定用乙醇-丙酮沉淀来纯化茶皂素。

At first it′s analyzed of the theasopoin′s decomposition temperature based on the quantitative in this paper. It is emphasized to take the theasapoin from the teacake by using the organic solvent-alcohol. The best concentrated temperature and vaccumity is found out. At last using ethanol-acetone solvent to precipitate the theasapoin by using the organic in order to purify it.
