中药材干燥过程中的活性成分变化机制研究现状

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

干燥是植物性中药材采收之后重要的加工工序,与中药材质量形成密切相关。干燥过程中植物多种抗胁迫机制的触发及其内部微生物的群落活动、物理化学变化等通常引起中药材中活性成分的显著变化,从而影响其药用价值。因此,认识中药材干燥过程中活性成分的变化机制,对调控其干燥品质、改进干燥方式具有重要意义。基于已有研究,该文综述了中药材干燥过程中活性成分的多种变化机制,以期为形成活性成分调控策略、提高中药材干燥技术水平、提升中药材质量提供参考。

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.
