Résumé
Free radicals are partially reduced form of metabolites of Nitrogen and Oxygen. These are highly reactive and potentially toxic compounds which are contributing factors in different chronic disease. The present study was aimed to determine antioxidant capability and reducing ability of coded polyherbal capsules [Arthitec 1 and Arthitec 2]. DPPH [2,2'-diphenyl-1-picryl hydrazyl] assay is most commonly used method for gauging antioxidant capability of natural compounds. In this assay DPPH act as stable free radical which react with an antioxidant. For measuring reducing ability suspected antioxidant react with ferric tripyridyltriazine [Fe3 +/- TPTZ] complex and convert ferric into ferrous. Results are evident that both capsule formulations Arthitec 1 and Arthitec 2 have promising antioxidant activity and reducing potential. Antioxidant potential of both coded capsules with varied concentrations [10, 50 and 100 microg/ml] were compared and in both cases scavenging activity and as well as reducing ability raised in a dose dependent manner just like standard Butylated hydroxyanisole [BHA]
