摘　　要：研究了采用乙醇-正己烷混合溶剂一步法同时提取茶籽饼中的茶皂素和茶籽油的方法,确定了最佳工艺条件。研究试验表明:当乙醇浓度为70%,乙醇水溶液与正己烷的体积比为1∶1,浸出时间120 min,浸出温度55℃,料液比1∶2(m/v),混合油分层温度25℃时,在此条件下提取的浸出茶籽粕皂素含量≤1.0%,残油≤1.5%。Extraction of camellia seed oil and tea saponin by ethanol and hexane mixture were studied and analyzed.The optimum conditions were as follows:ethanol concentration 70%,the volume ratio of ethanol solution and hexane 1∶1,extraction time 120 min,extraction temperature 55℃,the ratio of solvent and tea seed cake 2∶1(v/m),mixed oil layered temperature 25 ℃。 Under this condition,saponin and oil content of camellia seed meal was less than1.0%and 1.5%.
