Abstract:The investigation of Bejaranoa semistriata, a new genus in the tribe Eupatorieae, afforded in addition to known compounds a new furanoheliangolide, two epimeric 1-keto-heliangolides, two germacranolides, two nerolidol derivatives and a geranylnerol derivative. The structures were elucidated by spectroscopic methods and a few chemical transformations.
Keywords:Compositae  sesquiterpene lactones  heliangolides  germacranolides  diterpenes  geranylnerol derivative  nerolidol derivatives
