Extraction of cumaru seed oil using compressed propane as solvent

Abstract This study reports the oil extraction from cumaru seeds by compressed propane (CPE). Extractions were performed varying temperature (20, 40, 60?°C), pressure (2, 6, 10?MPa), and average particle size 1.7, 1.0, 0.5?mm). The results compared respect to coumarin content, total phenolic antimicrobial antioxidant activities. It was obtained that 98 % of present in can be recovered at 60?°C, 10?MPa, 0.5?mm. fatty acid profile indicated with CPE is richer unsaturated acids than samples Soxhlet n-hexane. Antimicrobial activity found against Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli. Antioxidant increased content both activities influenced presence (0.11?0.50?wt%). showed selective for low contents within constant rate period.
