目的 优选化湿败毒颗粒（Huashi Baidu Granules，HBG）的喷雾干燥工艺。方法 利用Box-Behnken设计-响应面法（Box-Behnken design-response surface method，BBD-RSM）设计实验，以药液相对密度、进风温度及进料速率为考察因素，得粉率、芍药苷、甘草素、大黄酚-8-O-β-D-葡萄糖苷、甘草酸、和厚朴酚和厚朴酚的转移率的综合评分为评价指标，优选最佳喷雾干燥工艺。结果 HBG的最佳喷雾干燥工艺为药液相对密度1.02，进风温度175℃，进料速率50%，验证试验的综合评分分别为92.57、92.50、91.96，各质量指标的RSD均小于3.0%。结论 该方法优选的喷雾干燥工艺稳定可行，可为HBG的制剂工艺提供参考。

Objective To optimize the spray drying process of Huashi Baidu Granules (HBG, 化湿败毒颗粒). Methods Box-Behnken design-response surface design (BBD-RSM) was used to select the best spray drying process by taking the relative density of liquid medicine, air inlet temperature and feed rate as the investigation factors, and the comprehensive score of powder yield, paeoniflorin, liquiritigenin, chrysophanol-8-O-β-D-glucoside, glycyrrhizic acid, honokiol and magnolol transfer rate as the evaluation index. Results The optimal spray drying process of HBG was as follows:the relative density of liquid was 1.02, the inlet air temperature was 175℃, the feed rate was 50%, the comprehensive scores of validation test were 92.57, 92.50, 91.96, respectively, and the RSD of each quality index was less than 3.0%. Conclusion The spray drying process optimized by this method is stable and feasible, which can provide reference for the preparation process of HBG.
