Abstract
In current study, we accepted out a systematic record of the relative antioxidant activity in selected medicinal plant species extracts. The total phenol varied from 25.3±7 to 278.4±7 mg g-1 in the extracts. Flavonoid contents were between 56±4.4 and 80.3±3.7. 1, 1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging result of the extracts was determined spectrophotometrically. The maximum radical scavenging consequence was observed in Metha pulegiam (Lamiacea) with IC50 = 0.018 mg ml-1. The strength of radical scavenging power of Metha pulegiam extract was about 4 times better than synthetic antioxidant butylated hydroxy toluene (BHT). The superior amount of phenolic compounds leads to further potent radical scavenging result as shown by Metha pulegiam leaves extract.
