A Review of Chemical Constituents in Ainsliaea Plants and Their Pharmacological Activities
Objective To review the chemical constituents and pharmacological effects of the plants of the genus Ainsliaea,with the aim of providing ideas and suggestions for the study of the chemical constituents of the genus and the development of new drugs based on its pharmacological effects.Methods A large amount of domestic and foreign literature of the last 40 years was searched,analyzed and then summarized and reviewed.Results The plants of the Ainsliaea contains a variety of active com-pounds,including sesquiterpenoids,triterpenoids,steroidal compounds and their derivatives,phenolic acids,flavonoids,anthraqui-nones,coumarins,lignans,essential oils,etc.Sesquiterpenes mainly include guaiacane type,zimerane type,eucalyptane type,pol-ymer sesquiterpene lactone and other sesquiterpenes.In addition,the plants of the genus Ainsliaea have various pharmacological effects,which mainly include antibacterial,anti-inflammatory,anti-tumor,and anti-obesity effects.Conclusion The plants of the genus Ainsliaea have been used medicinally for a long time,and have various chemical components and pharmacological activ-ities.The current research is limited to some species of the plants of Ainsliaea,and there are relatively few studies on the quality control of the plants of Ainsliaea.It may be considered to conduct the corresponding research on other species of this genus and comprehensively standardize the quality control of this genus.The existing literature is mostly limited to the analysis of the in vivo and in vitro mechanisms of individual compound.The research of the pharmacological effects of other compounds and their mech-anisms is not deep enough and needs further research.
