In this work we evaluated the antioxidant activity of absolute methanol extract and its fractions from the snapdragon (Antirrhinum majus) plant. The presence of total phenolics content, IC50 and the % inhibition in linoleic acid oxidation were evaluated. The antioxidant activity of plant extract and fractions was also studied using sunflower oil as an oxidative substrate. Peroxide value (PV), free fatty acids (FFA), conjugated dienes (CD), conjugated trienes (CT) and para-anisidine values were also determined by stabilising the sunflower oil as oxidation substrate. Moreover, it was observed to provide a protective effect in H2O2-induced oxidative damage in plasmid pBR322 DNA, indicating that the plant has antioxidant properties. The results of present study revealed that snapdragon plant may be considered as a good source of natural antioxidants.
