N2 - This study investigates the impact of geographical location on the nutritional quality, chemical composition, and antioxidant activity of Cucurbita maxima (rouge vif d'Etampes) seed oil. In terms of lipidic fraction, variations in fatty acid composition were observed across regions, with Guercif exhibiting the highest polyunsaturated fatty acid levels (57.78%) and El Jadida the lowest (44.21%). Guercif also had the highest β-sitosterol content (107.98 mg/100g oil), while total sterols were highest in Khemisset (314.92 mg/100g oil). Additionally, Guercif displayed the highest γ-tocopherol content (568.51 mg/kg oil). Physicochemical analysis revealed higher acid and peroxide values in El Jadida, along with lower iodine values. El Jadida also exhibited higher levels of carotenoids and chlorophyll. In terms of alcoholic fraction, guercif showed higher polyphenol content and strong free radical scavenging activity, while Khemisset demonstrated significant antioxidant activity (EC50 of 0.17 mg/mL). These findings underscore the importance of considering regional variations in future studies on pumpkin seed products.
