Abstract: Phytochemical study of the flowers of Gochnatia polymorpha subsp. floccosa, Asteraceae, yielded eleven known triterpenes identified as lupeol, lupeyl acetate, lupeyl palmitate, taraxasterol, taraxasteryl acetate, pseudotaraxasterol, pseudotaraxasterol acetate, alpha-amyrin, alpha-amyryl palmitate, beta-amyrin and beta-amyryl palmitate, along with sitosterol, stigmasterol, palmitic and stearic acids. These compounds are been reported for the first time in the species. The compounds were identified by analysis of NMR spectra ((1)H, (13)C and DEPT), GC-MS and comparison with literature data. Previous work have reported the isolation of triterpenes, diterpenes, sesquiterpenes, flavonoids, coumarins and phenolic compounds from aerial parts and roots from G. polymorpha.
