通过不同制备工艺的研究 ,确定对芪术胃安颗粒剂的最佳提取工艺。方法采用水提取 -醇沉淀、乙醇回流提取 ,以黄芪甲甙和延胡索乙素为指标成分 ,采用双波长扫描、紫外分光光度法测定黄芪甲甙及延胡索乙素含量。结果 :水提取 -醇沉淀法与乙醇回流法的优化结果比较 ,两种提取工艺的黄芪甲甙 ,延胡索乙素含量均无显著性差异。结论 :从生产实际出发 ,芪术胃安颗粒剂提取工艺应选用乙醇回流法即乙醇浓度为 50 % ,回流温度为 90℃ ,回流时间为 2小时为最佳条件。
Through the research of different preparation technology, the best extraction technology of Qizhuweian Granule was determined. Methods Aqueous extract - alcohol precipitation and ethanol reflux extraction were used. Astragaloside IV and tetrahydropalmatine were used as the index components. The contents of IVC and tetrahydropalmatine were determined by dual wavelength scanning and UV spectrophotometry. Results: The results of water extraction - ethanol precipitation and ethanol reflux comparison, the two extraction process of Astragalus, tetrahydropalmatine content had no significant difference. Conclusion: From the actual production, the technology of Qizhuweian Granules should be selected ethanol reflux method that ethanol concentration was 50%, reflux temperature was 90 ℃, reflux time of 2 hours for the best conditions.
