ABSTRACT: OBJECTIVE To optimize the drying process of Zishen capsules and to provide basis for the determination of the production process of Zishen capsules. Methods the effects of hot air drying, vacuum drying, microwave drying and spray drying on the quality of dry extract were studied with the properties of extract, yield, hygroscopicity, pinocoside and paeoniflorin as indicators.
Results: in the dry extract of hot air vacuum drying, microwave drying equipment and spray drying, the contents of spironicin were 0.0140%, 0.0220% and 0.0135% respectively. The paeoniflorin was 0.0475%, 0.0681% and 0.0700% respectively. Conclusion the yield and hygroscopicity of microwave drying dry extract are better than that of spray drying. The amount of index components is higher than that of vacuum drying and spray drying, and the best drying method is determined by microwave drying.
