摘要
目的:通过正交试验法优选出正柴胡饮口服液的最佳提取工艺。方法:以芍药苷的含量和干膏收率为指标,按正交表L9(34)设计试验,考察煎煮时间、煎煮次数、加水量3个因素。结果:得出最佳提取工艺为:用8倍量的水煎煮3次,每次0.5 h。结论:优选出的提取工艺合理可行。
Objective： To optimize the extraction process of Zheng-chai-hu oral liquid. Methods： The extraction process of Zheng-chai-hu oral liquid was optimized by L9 （3^4） orthogonal test with paecniflorin and the yield of extract as index, and with duration of decotion, times of decotion and the amount of water added as three factors. Results： The optimum extraction condition was the following, the amount of water added to which was 8 times that of medical material, and it was decocted 30 minutes each time for 3 times. Conclusion： The optimized extraction process is suitable and fea- sible.
