dos Santos, Anai L. published the artcileAnalysis of the seasonal variation in chemical profile of Piper glabratum Kunth essential oils using GCxGC/qMS and their antioxidant and antifungal activities, Related Products of alcohols-buliding-blocks, the main research area is Piper essential oil antioxidant antifungal seasonal variation.
Piper glabratum is a plant native from South America, which has been little studied, despite its use in folk medicine. In this study, chem. composition, antioxidant and antifungal activities of essential oils (EOs) from leaves of P. glabratum were investigated. The influence of seasonality on its chem. composition was also evaluated. The chem. characterization was performed by twodimensional gas chromatog. coupled with quadrupole mass spectrometry (GC×GC/qMS). Altogether, 199 compounds were identified in the EOs and their composition varied during the seasonal cycle. The main compounds found were sesquiterpenes and their oxygenated analogs. EOs showed antioxidant activity, measured by 2,2-diphenyl-1-picrylhydrazyl-DPPH (from 28.1 to 33.4 μg mL-1) and β-carotene assays (from 57.4 to 66.4%), and inhibitory action against C. albicans. The oils provided expressive properties; however, the yield of EO from winter was not enough for activities assays, remarking the influence of the seasonality on the biol. activities of this plant.
