Abstract

The antioxidant activity of crude aqueous leaves extracts of laurel (Laurus nobilis L.) and fig (Ficus carica L.) based on their concentrations was evaluated. For this purpose, the DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activity was used and the IC50 (corresponding to the concentration required to scavenge 50% of DPPH in the solution) of each extract determined. The results showed that the fig leaves extract could have the highest antioxidant activity with an IC50 of about 1.5 mg/ml. The IC50 of the bay leaves extract was about 2.8 mg/ml. The methanolic extract of Ginkgo biloba L., ascorbic acid (vitamin C) and BHT (butylated hydroxytoluene) were used as references
