Article Synopsis
- The study simulates the drying process of different grades of Angelicae Sinensis Radix using the Weibull distribution to understand their low-temperature moisture regain characteristics and how drying conditions affect them.
- It finds that lower drying temperatures lead to better simulation results, with temperature having a greater effect on moisture regain rates than the grade of the product.
- Additionally, at 40°C, the relative moisture regain rates are higher and follow the order of first class > second class > third class, with effective diffusion coefficients also varying by grade and temperature.

Article Synopsis
- Angelicae sinensis Radix (ASR) is a vital medicinal herb in Chinese medicine, particularly sourced from Gansu province.
- This study highlights how different drying methods significantly impact ASR's medicinal properties and overall quality.
- The traditional method of shade drying has evolved to "fumigation drying" as per the Chinese Pharmacopoeia, with new drying techniques emerging to better meet processing needs.
Objective: To study the characteristics of inorganic elements in different organs of Hedysarum polybotrys in different growing variation, including root, rhizome, leaf, flower and fruit.
Methods: The content of 13 inorganic elements in different organs were detected by using flame atomic absorption method, and then the characteristics of inorganic elements in different organs of Hedysarum polybotrys in different growing variation were analyzed.
Results: There were abundant inorganic elements in root, rhizome, leaf, flower and fruit, the change in the contents of inorganic elements at different growing variation related to the season.
