Guaianolide – type sesquiterpene lactones from the aqueous extract of Salcedoa mirabaliarum

Abstract

Salcedoa mirabaliarum is an endemic species to the island of Hispaniola. Continuing with the interest of our research group in the Asteraceae botanical family present on Hispaniola, a phytochemical study of the aqueous extract of the aerial parts of S. mirabaliarum was performed, affording five guaianolide–type sesquiterpene lactones detected for the first time in this species: dihydroestafiatone, zaluzanin C, dihydroestafiatol, isoamberboin, and 4–epi–dihydroestafiatol.
