We search data on chemical constituents and pharmacological effects of the genus Sonchus in recent years by the CAS Shanghai institute of materia database platform.The chemical constituents and pharmacological activities of the genus Sonchus were reviewed and analyzied. The chemical constituents of the genus Sonchus is more complex

so the current research focuses on sesquiterpene lactones and sesquiterpene lactone Glycosides. Its pharmacological research is now mainly in their antitumor and antioxidant effect. Now some plants from this genus have used as health food. This paper sums up the chemical structure

the main bio-activity and the distribution of chemical constituents according to the research on this genus over the last 20 years

hoping to give references for the further research and development of this genus.
