Abstract

This study investigated the lipid profiles and free radical scavenging potential of Coriandrum sativum fruit oils from Tunisia and Canada, utilizing three extraction methods: single screw, twin screw, and solvent extraction. Significant differences (p < 0.05) were found in the concentrations of essential fatty acids, including petroselinic, linoleic, oleic, and palmitic acids, between oils from the two regions. Notably, the twin screw extraction method applied to Tunisian coriander oils resulted in higher phytochemical content and superior free radical scavenging activity. The twin screw method demonstrated the highest efficacy, achieving an IC₅₀ value of 1.4 mg/ml for the stable DPPH radical, while the solvent extraction method yielded an IC₅₀ of 4 mg/ml for the same oil. These findings highlight the influence of geographic origin and extraction techniques on the nutritional and antioxidant properties of coriander oils.
