[Mechanisms of changes of active components in Chinese medicinal materials during drying: a review]

Abstract

Drying is an indispensable processing step for Chinese medicinal materials after harvesting. It often leads to significant changes in the active components of these materials, thus impacting their medicinal values. Understanding the mechanisms behind the changes during the drying process is of great importance for regulating the transformation of key active components. Therefore, this paper reviews the available studies and comprehensively expounds the mechanisms underlying the changes in active components during the drying process. The aim is to offer insights for the development of regulatory strategies and the improvement of drying techniques for Chinese medicinal materials.

Keywords: Chinese medicinal materials; active components; drying; physicochemical transformation; physiological effects.
