CALLE, Alberto; YUPANQUI, Jimena; FLORES, Yonny  e  ALMANZA, Giovanna R.. FLAVONOIDES DE BACCHARIS BOLIVIENSIS. Rev. Bol. Quim [online]. 2012, vol.29, n.2, pp.158-163. ISSN 0250-5460.

Two diterpenes and four flavonoids: 1 (5,7,3',4'-tetrahydroxy-6-methoxyflavanone; Filifolin), 2 (5,3'-dihydroxy-3,6,7,8,4'-pentamethoxyflavone), 3 (5,4'-dihydroxy-6,7,8-trimethoxyflavone; Xanthomicrol) and 4 (5,6,7,3',4'-pentahydroxyflavone; 6-Hydroxyluteolin), were isolated from the aerial parts of Baccharis boliviensis and identified by spectroscopic techniques of NMR 1D and 2D as well as by comparison with bibliographic data. The two diterpenes were previously reported in B. boliviensis while the four flavonoids are first reported in this species and being major secondary metabolites give a potential pharmacological interest because these compounds or similar compounds showed apoptotic or cytotoxic activity.
