ABSTRACT
Objective To investigate the effects of different drying methods on composition and content of five active constituents in root bark and root of Polgala tenuifoliaroot. Methods The contents of polygalaxanthone III, 3,6’-disinapoyl sucrose, polygalacic acid, senegenin, and tenuifolin in root bark and root from different drying samples were determined by HPLC. Then the data analysis was performed by ANOVA and TOPSIS methods. Results There is a difference in the order of drying methods for bark and root of P. tenuifoliaroot. For P. tenuifoliaroot root bark, the order of different drying methods was microwave drying > 60 ℃ hot-air drying > 50 ℃ hot-air drying > 70 ℃ hot-air drying > freeze-drying > 40 ℃ hot-air drying > shade drying > sun drying; For P. tenuifolia root, the different drying methods were sorted by microwave drying > 60 ℃ hot-air drying > shade drying > sun drying > 50 ℃ hot-air drying > 40 ℃ hot-air drying > 70 ℃ hot-air drying > freeze-drying. Conclusion Combined with the production practice, this study suggests that microwave drying and hot-air drying at 60 ℃ are suitable drying methods for P. tenuifoliaroot bark and root, providing a basis for the determination of drying methods for the origin processing of P. tenuifolia.
