Objective: To review the study on chemical constituents of the genus Petasites. Search was conducted in CNKI

Wanfang Data

SciFinder Scholar and library.The domestic and foreign literatures about chemical constituents of petasites in recent 20 years were reviewed. The genus Petasites

most of which are used as both food and medicine

distributed widely in China and have very high medicinal values.The main characteristic constituents of them are sesquiterpene

mostly bakkenolide-type

eremophilane-type and oplopane-type.Other characteristic constituents are triterpenoid

flavone

pyrrolizidine alkaloids

volatile oil and so on. The genus Petasites have been shown to have a defined pharmacological activity

and high value in nutrition.Its chemical components are complicated. It has a wide application prospect for food and drug on plants of Petasites.
