Because of its use in folk medicine and common cultivation in home gardens on the outskirts of Porto Velho - RO, this study aimed to extract, identify and quantify the essential oil of fresh roots, as well as its antioxidant activity. The extraction of essential oil from the roots was carried out by hydrodistillation in Clevenger apparatus modified. The analysis of the components of essential oil was by GC/MS and 25 allowed the identification of chemical components, most of which sesquiterpenes: (E) -anetol, (Z) -anetol, safrole, germacrene D-germacrene B and bicyclogermacrene, which showed higher levels compared to other constituents, and the dominant classes of the essential oils were monoterpenes, sesquiterpenes and phenylpropanoid. In the antioxidant activity test were determined effective concentrations (EC50) and Antioxidant Activity (% AA). The following CE50 and %AA values were found: Ginkgo biloba (used as reference) 46,96 mg.L- 1 and 75.26 mg.L-1 for the essential oil from the roots of P. marginatum. The methodology used for the antioxidant activity was adequate, and the essential oil showed significant antioxidant activity. 2016 artículo científico 0100-8307 https://www.redalyc.org/articulo.oa?id=467547716038 pt http://www.redalyc.org/revista.oa?id=4675 Ciência e Natura application/pdf Universidade Federal de Santa Maria Ciência e Natura (Brasil) Num.3 Vol.38 |
