摘要：http://dx.doi.org/10.5902/223611704201 Evaluation of the antioxidant activity and chromatographic profile of the Piper aduncum (false jaborandi) extracts. This paper describes the investigation of the chemical composition using the leaves of Piper aduncum (Piperaceae) through methods of extraction envolvind decoction, maceration and ultrasonic bath. The investigation was made by the gas chromatography-mass spectrometry/SPME. From these extracts, the antioxidant activity in the presence of a free radical DPPH was evaluated.
