摘要
为了经济有效地提取无患子皂苷，本实验采用分光光度计法测定无患子总皂苷含量，通过比较提取溶剂（水和乙醇），提取温度，料液比和物料打碎时间点，第一次浸泡时间，研究出无患子皂苷最佳提取工艺：55℃温度下用50％乙醇提取三次，料液比分别为1：5、1：3、1：1．5，提取时间分别为8、2h和1h，无患子总皂苷产率可以达到26．06％。粗提物纯度为36．31％。
To extract sapindus saponin economically and effectively,spectrophotometer was used to detect the content of sapindus-saponin in this study. Through comparing the parameters include extraction solvent （ water and ethanol）, extraction temperature, sample/liquid ratio and material breaking time and the first soaking time, the optimum extraction conditions of sapindus-saponins were as follows：three times extraction with 50% ethanol under 55℃ sample/liquid ratio was 1： 5,1 ： 3, and 1： 1.5, and 8 h, 2 h, and 1 h spent, respectively. Under this condition could reach the highest yield value of 26.06% of sapindus-saponin and 36.31% erode extraction purity.
