乳疾一贴灵巴布剂水提工艺

Extraction Technology of Ruji Yitieling Cataplasm

目的:优选乳疾一贴灵巴布剂的水提取最佳工艺条件。方法:采用L9(34)正交试验法,以羟基红花黄色素A的含量及浸膏得率为试验指标,考察浸泡时间、加水量、提取时间对水回流提取的影响,确定最佳提取条件。结果:最佳提取条件为浸泡1.5 h,第1次加10倍量水,提取1 h,第2次加8倍量水,提取0.5 h。结论:该优选工艺稳定、可行。

Objective：To optimize extraction technology conditions of Ruji Yitieling cataplasm.Method：Extraction conditions was optimized by L9（34） orthogonal design test.The content and dry extract rate of HSYA as indexes.Effects of soaking time,water volume,extraction time were investigated.Result：Optimum extraction technology was as followed：soaked 1.5 h,extracted 1 h with 10 times the amount of water in the first time,extracted 0.5 h with 8 times the amount of water in the second time.Conclusion：The optimum extraction technique was stable and feasible.
