A Review of Mill. Genus: Its Taxonomy, Chemical Constituents, and Pharmacological Effect Due to Processing Changes.

ETHNOPHARMACOLOGICAL RELEVANCE

The genus Tourn, ex Mill. contains numerous chemical components, such as steroidal saponins, polysaccharides, flavonoids, alkaloids, and others, it possesses diverse pharmacological activities, such as anti-aging, anti-tumor, immunological regulation, as well as blood glucose management and fat reducing properties.

AIM OF THE REVIEW

This study reviews the current state of research on the systematic categorization, chemical composition, pharmacological effects, and processing changes of the plants belonging to the genus , to provide a theoretical foundation for their scientific development and rational application.

MATERIALS AND METHODS

The information was obtained by searching the scientific literature published between 1977 and 2022 on online databases (including PubMed, CNKI, SciFinder, and Web of Science) and other sources (such as the 2020 edition, and Chinese herbal books).

RESULTS

The genus contains 79 species, and 233 bioactive chemical compounds were identified in them. The abundance of pharmacological activities, such as antioxidant activities, anti-fatigue activities, anti-inflammatory activities, etc., were revealed for the representatives of this genus. In addition, there are numerous processing methods, and many chemical constituents and pharmacological activities change after the unappropriated processing.

CONCLUSIONS

This review summarizes the taxonomy classification, chemical composition, pharmacological effects, and processing of the plants belonging to the genus , providing references and research tendencies for plant-based drug development and further clinical applications.
