摘　　要：采用超声波法,通过单因素试验和正交实验设计,研究超声波功率、乙醇浓度、料液比、提取时间对总皂苷提取率的影响,优选鸡骨草总皂苷提取的工艺条件。结果表明:超声波提取法的最佳提取工艺为:超声波功率90W,乙醇浓度50%,料液比1∶25(w/v),提取时间20min,在此工艺条件下皂苷提取得率为1.43%。To optimize the process conditions, the effect of extracting time, ultrasonic power, ethanol concentration and solid to liquid ratio on the extraction rate of total saponins from Abrus cantoniensis were studied using ultrasonic-assisted extraction process by single factor and orthogonal test. The results showed that the optimal conditions of total saponins extraction from Abrus cantoniensis was as follows：ultrasonic power 90 W,ethanol concentration 50 %,and solid to liquid ratio 1 25,extraction time 20 rain. Under these conditions,the extraction rate of total saponins was 1. 43 %.
