This study evaluated the candeia wood (Eremanthus erythropappus) oil extraction using supercritical extraction with CO2 and the addition of ethanol and ethyl acetate as cosolvents (1, 3 and 5% v/v). The experiments were performed at 70 degrees C and 24 MPa, with a mixture volumetric flow of 2 mL min(-1). The cosolvents increased the yield of extraction, obtaining up to 2.35 wt% with the addition of 5% ethanol, approximately 52% larger than the extraction with CO2. The extraction kinetic curves were satisfactorily represented by the Sovova mathematical model. In the extraction with 5% ethanol, it was possible to obtain the highest yield of alpha-bisabolol, 16.53 g kg(-1), an amount 41% higher than the extraction without cosolvent. The addition of ethanol and ethyl acetate to CO2 increased the amount of total phenolic content in the oil, and consequently, its antioxidant capacity. The oil fractionation by column chromatography was efficient for alpha-bisabolol isolation.
