Abstract:
Background: The active compounds of Cornus mas 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 β hydroxyl toluene (BHT, 100 mg/lit) were added into soybean oil, and the resulted
mixtures were incubated for 35 days at 65°C. Peroxide values (PVs) and thiobarbituric acidreactive
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 β-carotene-linoleic acid and DPPH assay
of the Cornus 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 Cornus mas L. while compared to the control.
