Abstract:
Nowadays, the emergence of allergies, side effects of chemical drugs, antibiotic resistantstrains, and the body s need for antioxidant compounds have emphasized the importance ofherbal medicine. In this study, antioxidant properties methanol extract of portulaca oleracea Land Colutea buhsei(boiss.) shap, two medical herbs, were investigated. Aerial parts of twoplants were collected in June 2017 from Mountains (Govinac around the Raz). The methanolicextracts of the two plants were prepared by maceration technique. After concentration withrotary, their antioxidant activity was assessed by two methods: 2, 2-dipheyil1-picryl hydrazyl(DPPH) [1] and ferric reducing antioxidant power (FRAP) [2,3]. Butylated hydroxy toluene(BHT) was used as a positive control. The IC50 value for the portulaca oleracea L. andColutea buhsei (boiss.) shap and BHT is 1.391, 0.716 and 0.012 mg per ml; respectively,while in the FARP method, the antioxidant activity informs of mmol Fe+2/g of extract for portulacaoleracea L. and for Colutea buhsei (boiss.) shap is calculated 269.27 and 692.79, respectively(The results are presented in Table 1). The results showed that antioxidant activityof two plant extracts of portulaca oleracea L. and Colutea buhsei (boiss.) shap less than BHT,also methanol extract of Colutea buhsei (boiss.) shap has an antioxidant activity higher thanportulaca oleracea L.
