Abstract
A leaf rinse extract with dichloromethane from Dimerostemma vestitum afforded five new eudesmanolides (1-5) along with the known flavone eupafolin. Compounds 1-5 were isolated by chromatographic methods, and their structures were elucidated by spectral analyses. Eudesmanolides 1-4 show a functional group substitution pattern so far unreported in the subtribe Verbesininae (tribe Heliantheae) of the family Asteraceae.Entities:
