Oxidative stability of sunflower oil as affected by Carica papaya leaves extracts during accelerated oxidative storageĪOAC. The highest antioxidant activity occurred in 70% ethanol extract. CP extracts i.e., methanolic, ethanolic, and water protected protective effect against oxidation of sunflower oil and can serve as substitutes for synthetic antioxidants. Results indicated that CP-Et 600 gave the lowest percentage change in AV, PV and T.B.A and the highest value in IV of sunflower oil, followed by CP-Mt 600 when compared with sunflower oil in the presence of the other antioxidant during the storage period. However, iodine values (IV) of the oils were markedly decreased. Analysis of heated sunflower oils demonstrated significant increases in peroxide values (PV), acid values (AV) and T.B.A. The bioactivities of the leaves extracts were attributed to their phytochemical constituents. Phytochemical screening of ethanol, methanol and aqueous extracts revealed the presence of phenol compounds, flavonoids, tannins, terpinoids, glycosides and steroides in ethanol and methanol extracts whereas Saponinns were present in methanol and aqueous extracts. Extraction was used by soaking method on CP leaves using distilled water, ethanol 70% v/v and methanol 80% v/v at 10% w/v concentration and qualitative test of phytochemical components. This research aims to study the potential of carica papaya (CP) leaves extracts for the prevention of sunflower oil oxidation. Papaya is normally known for its food and nutritional values throughout the world. Papaya ( Carica papaya L.) is normally called as paw-paw and it belongs to the family caricaceae.
