摘要: The effects of ultrasound-assisted, supercritical CO2 and solvent extraction techniques on antioxidant activity Eriobotrya japonica (Lindl.) skin extracts were investigated using 2, 2-diphenyl-1-picrylhydrazyl, β-carotene, Rancimat assays. Solvent extract at 400 ppm had the highest activity. was most effective method phenols tocopherols. Protective in stabilization soybean oil during frying determined by measuring its peroxide value, total polar compounds, carbonyl free fatty acids, conjugated dienes, trienes. Results indicated that exhibited stronger than tertiary butylhydroquinone.
