摘要
目的优选复方贞楼颗粒最佳提取工艺。方法采用正交试验法进行优选,高效液相色谱法测定女贞子中齐墩果酸的含量。结果最佳提取工艺为70%乙醇回流提取两次,每次2 h,第一次加7倍量,第二次加5倍量。结论该提取工艺稳定、合理、可行。
Objective To investigate process of the optimal extraction for Compound Zhenlou granules. Methods The orthogonal test was employed for selecting the optimal extraction process and the contents of Oleanolic acid was determined by HPLC. Results The optimal extraction condition obtained is adding 12 times amount of 70% alcohol and 2 hours for each time, then adding sevenfold volume of 70% alcohol at first time and five volume of 70% alcohol at second time. Conclusion The method is stable, reasonable and feasible.
