To provide a scientific basis for the selection and optimization of the modern drying processing method for Angelicae Sinensis Radix (ASR). Three phenolic acids (esters), 6 phthalides were determined by using UPLC-PDA while polysaccharides were determined by UV-Vis spectrophotometry. Then the effects of drying methods on the inner qualities of ASR were evaluated through principle components analysis (PCA) combined with the appearance properties after drying.

Article Synopsis
- * Results indicated that drying methods significantly affect the levels of key compounds, with hot-air drying proving more effective than microwave and infrared drying, particularly at lower temperatures (40-45 °C).
- * The TOPSIS statistical evaluation determined that the optimal drying method for MHH is the variable temperature hot-air process at 45-60 °C, which enhances the preservation of volatile compounds in the herb. *
To establish the water dynamics model for drying process of Angelicae Sinensis Radix, the Weibull distribution model was applied to study the moisture ratio variation curves, and compared the drying rate and drying activation energy with the drying methods of temperature controllable air drying, infrared drying under different temperatures (50, 60, 70 degrees C). The Weibull distribution model could well describe the drying curves, for the moisture ratio vs. drying time profiled of the model showed high correlation (R2 = 0.
