Abstract

LIMBERGER, Renata P. et al. Essential oils from Myrcia species native to Rio Grande do Sul. Quím. Nova [online]. 2004, vol.27, n.6, pp.916-919. ISSN 0100-4042.  http://dx.doi.org/10.1590/S0100-40422004000600015.

Essential oils from M. richardiana, M. arborescens, M. selloi, M. oligantha, M. rostrata, M. lajeana, M. obtecta, M. pubipetala and M. hatschbachii were obtained by hydrodistillation and analyzed by GC and GC/MS. Sixty-seven compounds have been identified ranging from 90-99% of the oil contents. All analyzed species were rich in cyclic sesquiterpenes (66-99%), mainly those from the cadinane, caryophyllane and germacrane cyclization pathway, among them b-caryophyllene, germacrene D, bicyclogermacrene, d-cadinene, spathulenol, caryophyllene oxide, globulol and a-cadinol. The acyclic sesquiterpene series was well represented by M. lajeana (32.1%), with 25,3% of (E)-nerolidyl acetate.

Keywords : Myrcia; essential oil; Myrtaceae.
