摘要
目的:优选超声波提取无患子中总皂苷的最佳工艺。方法:通过正交设计实验,以溶剂体积分数、超声时间、超声功率以及料液比作为影响因素,以总皂苷提取率作为参考指标,优选最佳工艺方案。结果:最佳提取工艺是90%乙醇,料液比为1∶20,90 W功率下超声40 min,其验证实验平均提取率为37.28%。结论:超声提取方法提取率高,结果稳定。
Objective： To optimize the best ultrasonic extraction technology of Sapindus con-saponin. Method： To determine the optimal extraction process, discussed the Influence of solvent volume fraction, ultrasonic time, ultrasonic power and material liquid by orthogonal design experiment. Result： Optimum extracting condition： 90% of ethanol, the material liquid than 1：20 and 40 minutes with ultrasound 90w power, the average extraction rate of validation experiments is 37.28%. Conclusion： This optimized process is stability, high extraction efficiency.
