摘要

Croton zehntneri Pax et Hoff is indigenous to the Northeastern of Brazil; its popular name is 'canela de Cunha' (cinnamon of Cunha). The specie is rich in anethole and is largely used in cooking to impart flavor to a variety of foods; the infusion of its leaves is used in folk medicine to treat manifestation that involve from a simple indigestion up to cases of insomnia. In this work the volatile oil from C. zehntneri was extracted using pressurized CO_2. Both kinetic and solubility experiments were performed using a fixed bed extractor. The composition of the volatile oil was determined using gas chromatography coupled to mass spectrometry. At 15℃ and 66.7 bar the solubility for the system C. zehntneri + CO_2 was 28.3X10~(-3) kg/kg and the global yield was 3.4% (mass). The volatile oil contained predominantly (E)-anethole (up to 88.9 %, area) and small amounts of sabinene, myrcene, 1, 8-cineole, (E)-beta-ocimene, alpha-terpineol, methyl chavicol, (Z)-anethole, delta-elemene, beta-elemene, trans-caryophyllene, germacrene D, alpha muurolene, beta-bisabolene.
