Sesquiterpene Lactones from Staehelina fruticosa

摘要: The phytochemical analysis of Staehelina fruticosa led to the isolation four germacranolide-type sesquiterpene lactones (1–4), including two new glycosides. structures these were elucidated using spectroscopic techniques, and enzymatic hydrolysis was carried out confirm nature glycoside derivatives. Molecular modeling incorporated substantiate their relative configuration.
