摘　　要：[目的]多指标综合优选芪防鼻敏颗粒的水提醇沉工艺。[方法]以黄芪甲苷、芍药苷提取率为指标,考察提取工艺条件;以黄芪甲苷、芍药苷转移率为指标,考察醇沉条件。[结果]最佳水提醇沉工艺为饮片加12倍加水量,提取3次,每次1.5 h;浓缩液相对密度为1.15～1.20（60℃）时,加乙醇为60%。[结论]该工艺稳定可行,可为芪防鼻敏颗粒的工业生产提供科学依据。[Objective] To investigate the technology of optimal water extraction and alcohol precipitation for Qifang Bimin granules with Multi-index. [Methods] The study employed the extraction rate of astragaloside IV and paeoniflorin as evaluation indexes to investigate extraction conditions. We also investigate alcohol precipitation condition in the metastatic rate of astragaloside IV and paeoniflorin as detective index. [Results] The optimal water extraction and alcohol precipitation was extracted 3 times, with 12 folds the amount of water,1.5 h for each time. The extracts were concentrated to the relative density of 1.15 ～1.20（60 ℃） with the concentration of alcohol precipitation 60%. [Conclusion] Optimized water extraction and alcohol precipitation technology was reasonable and feasible and it could provide a reference for industrial production of Qifang Bimin granules.
