摘要
以95%乙醇-丙酮混合溶剂提取茶皂素,得到了混合溶剂(95%乙醇与丙酮)最佳配比为4∶1。在最佳配比下,考察提取时间、温度、液料比对产率和纯度的影响,并采用正交试验进行优化,以产率为指标,得到优化的提取工艺为液料比4∶1,浸提时间3.5h,温度70℃,此时茶皂素产率可达33.3%;以纯度为指标,得到优化的提取工艺为液料比4∶1,浸提时间2.5h,温度60℃,此时茶皂素纯度为97.9%。
The mixture of 80% ethanol （95%） and 20% acetone is selected as extracting agents to investigate the effects of extracting time, temperature and ratio of volume to weight on theasaponin extraction. The orthogonal experiments result in optimum conditions as follows： according to the yield, volume to weight ratio of 4：1, extracting time 3.5 h and temperature 70 ℃, the yield is up to 33.3%. According to the purity, volume toweight ratio of 4：1, extracting time 2.5 h and temperature 60 ℃C, the purity is up to 97.9%.
