摘要: 以无水乙醇为提取剂并采用改进的胆甾醇纯化法,得到了精制茶皂素。40.0g油茶籽粉经脱油处理后用300mL无水乙醇提取,所得粗品经索氏抽提除杂并制得皂素-胆甾醇复合物(投料质量比为胆甾醇:皂素=0.75:1)。以甲苯为溶剂再次索氏抽提分离该复合物,同时得到纯度为98.5%以上的茶皂素精品。

Abstract: Method on extraction and purification of tea saponin by using anhydrous alcohol as solvent and cholesterol as purifying agent was reported. Tea seed powder was treated with acetone to remove tea oil followed by extracting tea saponin with alcohol. The crude product was purified by Soxhlet extraction with cholesterol (cholesterol tea saponin 0.75:1) to obtain tea saponin of over 98.5% purity.

Key words: tea saponin, purification, anhydrous alcohol, cholesterol
