Chemodiversity of essential oils from nine species of Celastraceae.

Abstract

Extracts and compounds obtained from several species of Celastraceae family are reported as potential sources of drugs due to their diverse pharmacological properties. Nevertheless, essential oil composition from these species is still little known. This work aimed the analysis of essential oils obtained from different Brazilian Celastraceae species. A total of seventeen oils were obtained using hydrodistillation process and analyzed by gas chromatography/mass spectrometry (GC/MS). Principal component analysis (PCA) allowed the identification of a chemical composition pattern among the analyzed essential oils. Some compounds were more frequent among Celastraceae species, such as cis and trans-oxide linalool (14/17 oil samples), nerylacetone (13/17), linalool (11/17), β-ionone (10/17), α-ionone (9/17), nerolidol (10/17), decanal (10/17) and dodecanoic acid (10/17). These results contribute to the chemophenetics of Celastraceae species.
