Abstract:
Objective To study the chemical composition from leaves of Smallanthus sonchifolius.Methods Some chromatography methods were used in the isolation procedure,while the structures were determined on the aids of NMR and MS spectral analyses.Results A new compound,together with five known compounds,was isolated from the ethanolic extract of the leaves.The new compound is characterized as 5,8-dihydroxyl-(5H,8H)-?-ionol(Ⅰ).Other compounds are obtained for the first time from the title plant and identified as ent-kaurane-3?,16?,17-triol(Ⅱ),entkaurane-16?,17-diol-19-oic acid(Ⅲ),3,4-dihydroxybenzaldehyde(Ⅳ),1-pentacosanol(Ⅴ),and 1-octacosanol(Ⅵ),respectively.Conclusion Compounds Ⅰ-Ⅵ are isolated from the plants of genus Smallanthus for the first time.Compound Ⅰ is a ?-ionol derivate firstly isolated from genus Smallanthus.It is named as sonchifolol.
