The phytochemical study of the aqueous extract of Salcedoa mirabaliarum (aerial parts), afforded five guaianolide– type sesquiterpene lactones: dihydroestafiatone, zaluzanin C, dihydroestafiatol, isoamberboin, and 4–epi– dihydroestafiatol, detected for first time in this species. The chemical structures were identified using 13C Nuclear magnetic resonance by comparison with previously reported data.
Key words: Salcedoa mirabaliarum, dihydroestafiatone, zaluzanin C, dihydroestafiatol, isoamberboin, 4-epi-dihydroestafiatol.
