Abstract

Background: It has been considered by researchers to study the possibility of replacing chemical food additives (synthetic antioxidants) by natural products (medicinal plants).Objective: This study investigated the antioxidant properties of SATUREJA HORTENSIS L. essential oil (SHEO) on SAFFLOWER OIL oxidation.Methods: Different assays have been used to evaluate the ANTIOXIDANT ACTIVITY of SHEO: total phenol content (TPC), DPPH·, ABTS+·, ferric thiocyanate (FTC), b-carotene bleaching. For evaluation of SHEO effect on SAFFLOWER OIL oxidation, peroxide value (PV), conjugated dienes (CD), and tiobarbituric acid (TBA) indices were compared with BHT (a synthetic antioxidant).Results: TPC of SHEO was determined to be 293.7 mg gallic acid equivalent in 1 ml of sample and IC50 was 0.71 mg/ml in DPPH·. 0.4 and 0.1 mg/ml of SHEO at all time (1, 5, 10, 15 min) showed the highest and lowest antiradical ABTSo+ activity (118.2 and 26.6 mg/ml AscAE =Ascorbic acid equivalent) in 15 min. In FTC and FTC-TBA, 8 mg/ml SHEO showed the highest activity. In b-carotene bleaching of 0.1-2 mg/ml SHEO, 0.1 has the minimum (%9.02), and 1 and 2 has the maximum inhibitory effects (%34.33 and %36.86 inhibitions). 4 mg/ml of SHEO had the highest inhibitory effect in the SAFFLOWER OIL test and that peroxide does not have significant difference with 0.1 mg/ml BHT.Conclusion: Antioxidant activities of SHEO concentrations increased in all indices (p<0.05) and various concentrations were able to slow down the oxidation process.
