摘要:
以绞股蓝全草为原料,采用微波和超声波对绞股蓝总皂甙提取进行了对比研究,两种方法分别采用单因素实验及正交试验,探讨了优化提取条件和参数。 结果表明:微波提取的优化工艺参数,料液比为1g∶25mL,微波处理时间为11min,微波功率为400W,总皂甙提取率为7.59 %;超声波提取的优化工艺参数,料液比为1g∶25mL,提取温度为70℃,超声波处理时间为20min,超声波功率为400W,总皂甙提取率为8.01%。

Abstract:
The microwave and ultrasonic techniques were used to extract Gypenosides from Gynostemma pentaphyllum (Thunb.) makino. The optimum extraction conditions were investigated by the single facter and orthogonal design. The optimal conditions for the microwave extraction were the ratio of material to solvent of 1∶25 (g/mL), extracting time of 11 min , microwave power of 400W. Under the optimal conditions, the rate of Gypenosides was 7.59%. The optimal conditions for the ultrasonic extraction were as follows: the ratio of material to solvent of 1∶25 (g/mL), extracting temperature of 70℃, extracting time of 20 min, ultrasonic power of 400W. Under the optimal conditions, the rate of Gypenosides was up to 8.01%.
