Comparative Study on Functional Components, Physicochemical Properties and Antioxidant Activity of <i>Amaranthus Caudatus</i> L. Oils Obtained by Different Solvents Extraction

Functional compositions, physicochemical properties and antioxidant activities of Amaranthus caudatus L. oils (ACO) obtained by different solvents were comparatively investigated. All the resulted ACO enrich in 75% unsaturated fatty acid squalene about 4 g/100 g. Different showed varying oil extraction, where acetone results a highest yield 6.80 extracted ethanol tocopherol (1351.26 mg/kg), polyphenols (211.28 mg/kg) (42519.13 mg/kg). However, phytosterols hexane (27571.20 was higher than that (19789.91 (22015.73 petroleum ether (24763.30 Furthermore, activity also measured DPPH, ABTS FRAP assay. According to principal component correlation analysis, correlated with DPPH scavenging ability, but tocopherols ferric reducing ability oils, respectively. This study provides promising excellent source functional for food industries.
