Incorporation Of Cornus Mas L. In Soybean Oil: Evaluation Of Phytochemical And Antioxidant Activity

Background: The active compounds of Cornus mos L. were extracted by the aid of water and ethanol and were incorporated into soybean oil samples. Afterward, their antioxidant activities were examined.Methods: The 1. 1 diphenyl-2- picrylhydrazyl (DPPH) and beta -carotene methods were approached in order to assess the antioxidant capacity. Different concentrations of extracts prepared (0,200, 400 and 800 mg/lit) and p hydroxyl toluene (BHT, 100 mgllit) were added into soybean oil, and the resulted mixtures were incubated for 35 days at 65 C. Peroxide values (PVs) and thiobarbituric acid reactive substances (TBARs) levels were measured each week during the incubation. The collected data from each incubation was analyzed using ANOVA test.Results: Results demonstrated that corresponded values for p-carotene-linoleic acid and DPPH assay of the Corpus mas L. extracted by ethanol and water were lower than synthetic antioxidant and BHT.Conclusion: PVs and TBARs levels of soybean oil during the incubation time was decreased by the incorporation of extracts (water and ethanol) of forms mas L. while compared to the control.
