正交试验优选补肾活血片的制备工艺

Optimization of Preparation Technology of Bushen Huoxue Tablet by Orthogonal Test

目的:优选补肾活血片制备工艺。方法:以加水倍数、提取时间、提取次数为因素,浸膏质量为指标,采用L9(34)正交试验优选补肾活血片的制备工艺。结果:补肾活血片水提最佳工艺条件为加10倍量水,煎煮2次,每次1 h。结论:该制备工艺简便、合理,可用于补肾活血片的制备。

OBJECTIVE： To optimize the preparation technology of Bushen huoxue tablet. METHODS： The extraction technology of Bushen huoxue tablet was optimized by L9（3^4） orthogonal test with amount of water, extraction time and extraction times as factors using the quality of extract as index. RESULTS： The optimal extraction technology was as follows： adding 10-fold water, decocting for 2 times, each 1 time. CONCLUSIONS： The extraction technology is simple and reasonable, and can be used for the preparation of Bushen huoxue tablet.
