目的:优化十味宝胶囊的提取及喷雾干燥工艺。方法:采用正交试验以黄芪甲苷、挥发油含量为指标优化提取工艺,以喷雾干燥粉成品的含水量为指标优化其喷雾干燥工艺结果:最佳提取条件为:12,10倍水提取2次,第1次提取4 h,第2次提取2 h;最佳喷雾干燥工艺条件为:进风温度为150℃,排风温度为70℃,浸膏相对密度为1.05 g·ml~(-1)。结论:本试验确定的生产工艺合理可行。
Objective: To optimize the extraction of Shiweibao capsule and spray drying process. Methods: The orthogonal test was used to optimize the extraction process with the content of astragaloside and volatile oil. The spray drying process was optimized with the water content of spray dried powder as the index. The optimum extraction conditions were 12 times and 10 times of water extraction , The first extraction 4 h, the second extraction 2 h; the best spray drying process conditions: inlet temperature of 150 ℃, exhaust temperature of 70 ℃, the relative density of the extract was 1.05 g · ml -1 ). Conclusion: The production process determined in this experiment is reasonable and feasible.
