Silva,Celia E. L. da; Minguzzi,Sandro; Silva,Rogério C. L. da; Matos,Maria F. C.; Tofoli,Danilo; Carvalho,João E. de; Ruiz,Ana L. T. G.The essential oil of roots of Jatropha ribifolia, obtained by hydrodistillation, was characterized in terms of its chemical composition by chromatographic method with flame ionization detection (GC-FID) and gas chromatography coupled to electron ionization mass spectrometry (GC-MS). The analyses and identification pointed by mass fragmentation pattern and retention index revealed the presence of 49 compounds, r...
