目的 :优选糖渴清片处方中B组药物水提取工艺条件。方法 :以总黄酮含量和浸膏总重的综合结果为考察指标 ,以紫外分光光度法为测定方法 ,选用L9(34 )正交表对水提取条件进行正交试验。结果 :最佳提取工艺条件为A3B1 C3。即加水 15倍量 ,煎煮 3次 ,煎煮总时间为 3h(第 1次加水 9倍量 ,煎煮 1.5h,第 2次加水 4倍量 ,煎煮 1h ,第 3次加水 2倍量 ,煎煮 0 .5h)。结论 :优选的水提取工艺条件合理、稳定、可行
Objective : To optimize the water extraction process conditions for Group B drugs in the recipes for sugar and thirst clearance. Methods : The combined results of total flavonoids content and total weight of the extracts were used as indexes, and UV spectrophotometry was used as the method of measurement. The orthogonal test of water extraction conditions was performed using the orthogonal L9 (34) table. Results : The optimum extraction conditions were A3B1 C3. That is, add 15 times the amount of water, boiling 3 times, the total boiling time is 3h (the first time to add water 9 times, boiling 1.5h, the second time to add water 4 times, boiling 1h, 3 times the amount of water added 3 times , Boiling 0. 5h). Conclusion : The optimal water extraction process conditions are reasonable, stable and feasible
