Abstract:
The quality of Chinese medicinal materials is related to the environment， with an optimal quality under adversity. The origin of Chinese medicinal materials has converted from wild collection to cultivation， and a better cultivation environment leads to a decline in their quality. At present， there are few effective methods to improve the quality of Chinese medicinal materials. Plants are bound to produce a large amount of reactive oxygen species （ROS） under adversity， and the quality improvement of Chinese medicinal materials under adversity may be achieved through ROS. This paper described the relationship between plant adversity-ROS-secondary metabolism： ROS can alter the structure of proteins （including enzymes） and regulate enzyme activities， thus affecting secondary metabolism to improve the adaptive capacity of plants. Therefore， ROS is the essential cause of adversity changing secondary metabolism. The cells of plants are omnipotent， and the medicinal parts of plants can independently complete the whole process of secondary metabolism， so regulation of secondary metabolism during the processing of fresh Chinese medicinal materials can significantly improve the quality of Chinese medicinal materials. Exogenous ROS can be used as inducible factors to stimulate medicinal parts， inducing a physiological state of fresh medicinal parts similar to that under adversity， thus enhancing secondary metabolism， and improving the contents of active ingredients in Chinese medicinal materials. In addition， the content and ratio of each ingredient in Chinese medicinal materials are closer to those of wild Chinese medicinal materials. The mechanism of plant adaptation to adversity is the mechanism of the quality formation of Chinese medicinal materials， and the application of ROS as inducible factors can provide a new pathway for the production of high-quality Chinese medicinal materials.
