SILVA, Luana B. et al. Triterpenes from the flowers of Gochnatia polymorpha subsp. floccosa. Rev. bras. farmacogn. [online]. 2011, vol.21, n.3, pp.556-559.  Epub Mar 04, 2011. ISSN 0102-695X.

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, α-amyrin, α-amyryl palmitate, β-amyrin and β-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 (1H, 13C 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.

Keywords : Gochnatia polymorpha subsp. floccosa; Asteraceae; triterpenes.
