The Sesquiterpenes of Ginseng

Abstract

Abstract The sesquiterpenes of ginseng have been studied. From the volatile oil, fifteen compounds were characterized. Three of those compounds, α-panasinsene,β-panasinsene and β-neoclovene, were new compounds and were characterized in this paper. Panasinsenes are considered as intermedial compounds in isomerization of caryophyllene to neoclovene.
