The extracts of seven Citrus rootstock seeds have been compared regarding fattyacid profile and antioxidant potential. Sour orange (Citrus aurantium L.) wasfound to contain the highest oil amount (34%), while the Poncirus trifoliatacultivars contained the highest percentage of unsaturated fatty acids (84–87%).In addition, the antioxidant properties of the extracts from defatted seeds havebeen evaluated by measuring their radical scavenging activity against 2,20-diphenyl-1-picrylhydrazyl. The highest antioxidant activities were observed in thecase of the acetone extract of sour orange and Citrumelo Swingle (76% and 75%,respectively), at a concentration of 0.17mgmL1. Moreover, the total phenoliccontent of the extracts, determined using the Folin–Ciocalteau reagent, was foundto be correlated with the radical scavenging activity results. The acetone extractsof sour orange and Citrumelo Swingle exhibited the highest phenolic content[112.3 and 103.4mg gallic acid equivalent g1 dry sample weight, respectively].

Abstract

The extracts of seven Citrus rootstock seeds have been compared regarding fattyacid profile and antioxidant potential. Sour orange (Citrus aurantium L.) wasfound to contain the highest oil amount (34%), while the Poncirus trifoliatacultivars contained the highest percentage of unsaturated fatty acids (84–87%).In addition, the antioxidant properties of the extracts from defatted seeds havebeen evaluated by measuring their radical scavenging activity against 2,20-diphenyl-1-picrylhydrazyl. The highest antioxidant activities were observed in thecase of the acetone extract of sour orange and Citrumelo Swingle (76% and 75%,respectively), at a concentration of 0.17mgmL1. Moreover, the total phenoliccontent of the extracts, determined using the Folin–Ciocalteau reagent, was foundto be correlated with the radical scavenging activity results. The acetone extractsof sour orange and Citrumelo Swingle exhibited the highest phenolic content[112.3 and 103.4mg gallic acid equivalent g1 dry sample weight, respectively].
