Abstract:Objective To optimize the alcohol precipitation and drying process of Shiwei Ehuang Granules.Methods Taken the content of Astragaloside A in Shiwei Ehuang Granules as the indexes,the orthogonal design was used to examine the effect of four factors(relative density of the ointment,added alcohol concentration,alcohol precipitation content and standing time after alcohol precipitation)on the alcohol precipitation process of the product,so as to determine the best process of alcohol precipitation for Shiwei Ehuang Granules.The effect of different drying methods and temperature on the content of Astragaloside A in dry ointment was studied to determine the best drying process for the product.Results The optimal alcohol precipitation process of Shiwei Ehuang Granules was as follows:1.10-1.15(80°C)relative density of ointment,adding 95%alcohol to make alcohol content 70%,and 12 h alcohol precipitation time.The optimal drying process of Shiwei Ehuang Granules was decompression drying,and the drying temperature was 85℃.The average content of Astragaloside A in three batches of products according to above optimized alcohol precipitation and drying process was 5.48 mg/g,and RSD was 1.74% (n=3).Conclusion Shiwei Ehuang Granules produced according to the optimized alcohol precipitation and drying process contain the effective components corresponding to the prescription,whose quality is stable and suitable for mass production.Therefore,the process is reasonable and feasible.
