ABSTRACT: OBJECTIVE To investigate the effects of five drying methods, i.e. sun drying, shade drying, hot air drying (40, 50, 60, 70 C), microwave drying and freeze drying, on the main chemical constituents of Polygala tenuifolia and its roots. METHODS The components and contents of polygalone III, 3,6’-dimustinoyl sucrose, polygallic acid, polygalactoside and polygalactoside in Polygala tenuifolia were determined by HPLC with different drying methods. The data were analyzed by one-way ANOVA and TOPSIS.
Result There were differences in the optimum order of drying methods between Radix Polygalae and its roots. The order of the effects of different drying methods on the active ingredients was Microwave Drying Equipment > 60 C hot air drying > 50 C hot air drying > 70 C hot air drying > freeze drying > 40 C hot air drying > shade drying > sun drying. In Radix Polygalae, the order of different drying methods was microwave drying > 60 C hot air drying > freeze drying. Shade drying > sun drying > 50 C hot air drying > 40 C hot air drying > 70 C hot air drying > freeze drying.
