In Vitro Antioxidant Activities of Two Medicinal Plants on the Basis of DPPH Free Radical Scavenging Activity

Abstract

The 2,2-diphenyl-1-picrylhydrazyl (DPPH) Free radicals are atoms or molecules that have one or more unpaired electrons on its outer orbital, highly reactive, and could damage cell inside human body. A Human Healthy body produce antioxidant to neutralize free radicals, but human ageing and stress oxidative conditions would increase the formation of free radicals. In The present research was used o.sanctum leaf , T.chebula plant powder Hydro alcoholic extract and with ascorbic acid in standard form; inhibition caused by The IC50 value of ocimum sanctum leafy have 47.235and Terminalia chebula have 63.18 compared to ascorbic acid having 22.03. The objectives of this research were to determine antioxidant activities of aerial part of using DPPH method,These findings support the ethnomedical use of this plant to promote good health.
