Characterization of Phenolic Profile and Antioxidant Potential of Some Algerian Olive Oils Cultivars

Olive oil is a source of antioxidants and poses positive effects on human health. The objective of this study was firstly to identify and quantify the phenolics of some Algerian olive oils; secondly, the antioxidant activity of the samples was assessed.
The virgin olive oils used in this study were derived from three Algerian cultivars, including Azeradj, Bouchouk, and Chemlal. After preparation of the samples, the phenolic, ortho-diphenol and flavonol contents in addition to phenolic profile were determined. Also, antioxidant capacity, reducing power, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity values were analyzed. Statistical analysis of the data was done with Statistica 5.5 Fr.
The phenolic contents of analyzed olive oils showed significant differences (p Both Chemlal and Azeradj Algerian olive oil cultivars can be considered as appropriate sources of bioactive phytochemicals, which play a major role in human health as free radical scavenger and can replace synthetic antioxidant in the food products.
