目的:研究舒筋活络颗粒最佳提取工艺。方法:采用正交试验设计,以路路通酸含量、干膏得率为指标,考察乙醇浓度、溶剂用量、提取时间、提取次数4个因素对舒筋活络颗粒提取效果的影响,优选提取工艺。结果:最佳工艺条件为加6倍量40%乙醇,提取3次,每次1 h。结论:该提取工艺合理可行,并能较好的保证制剂质量。
Objective: To study the best extraction process of Shujin Huoluo granules. Methods: Using orthogonal experimental design, taking the acid content and the dry extract yield as the indexes, the effects of ethanol concentration, solvent dosage, extraction time and extraction times on the extraction efficiency of Shujin Huoluo granules were investigated. The optimal extraction process . Results: The optimal conditions were 6 times the amount of 40% ethanol, extracted three times, each time 1 h. Conclusion: The extraction process is reasonable and feasible, and can better ensure the preparation quality.
