Composição química do óleo volátil de Myrcianthes nativas da região sul do Brasil

Abstract: RESUMO:O óleo essencial das folhas de Myrcianthes gigantea (Myrtaceae), coletadas no Rio Grande do Sul, foi obtido por hidrodestilação em Clevenger e analisado por CG/detector de ionização de chamas e CG/EM. Trinta e seis compostos foram identifi cados, totalizando 90,1% do conteúdo do óleo. A composição do óleo demonstrou predominância de sesquiterpenos cíclicos, principalmente da via de ciclização do germacrano, apresentando espatulenol (28,8%) e seu isômero, iso-espatulenol (9,5%), como principais constitui… Show more

“…Th is high concentration has been suggested as the reason of the high bioactivity of orange peel essential oil (Tsai 2008). Limonene is also present in the essential oils of non-citric species (Agostini et al 2005;Apel et al 2005;Apel et al 2006;Carvalho Filho et al 2006;Silva et al 2009), which are frequently associated with high inhibitory eff ects (Azirak & Karaman 2008;Silva et al 2009;Souza Filho et al 2009). To the best of our knowledge, there has been no allelopathic study that used isolated limonene, but it is reasonable to propose that this was the main compound responsible for the allelopathic eff ects found (because we used a purifi ed version of the orange peel essential oil, one might choose to call this a phytotoxic eff ect).…”
