Bran of different rice cultivars produced in Portugal were used to study supercritical carbon dioxide extraction conditions of rice bran oil (RBO) and evaluate and compare antioxidant activity and fatty acid composition of the different rice bran varieties. The effect of plant loading (10–20 g), CO2 flow rate (0.5–1.5 L/min), pressure (20–60 MPa), and temperature (40–80 °C) was studied. The amount of oil extracted ranged from 11.72%, for Ariete cultivar, to 15.60%, for Sirio cultivar. The main fatty acids components obtained were palmitic (13.37%–16.32%), oleic (44.60%–52.56%), and linoleic (29.90%–38.51%). Excellent parameters of the susceptibility to oxidation of the oils were obtained and compare. RBO of Ariete and Gladio varieties presented superior DPPH and ABTS radical scavenging activities, whereas, Minima, Ellebi, and Sirio varieties had the lowest scavenging activities. Moreover, the oil obtained towards the final stages of extraction presented increased antioxidant activity.

Medicinal plants particularly with higher nutritional values are attracting the attention of both the pharmacological and nutritional affairs. In the present study, we extracted the wheat germ oil with cold press, hexane as well as supercritical carbon dioxide (SC-CO2). All were chemically and biologically (antimicrobial) evaluated to investigate how far can the differential in fatty acid composition affect the biological properties. The most eminent result was recorded by SC-CO2 oil. It was the only among the extracted oils that possessed moderate antibacterial and strong antifungal activities.
