Abstract

Peptides test drug 1, 2, 3 and 4 coded as RK, KH, RRH, and RRK were subjected to in-vitro antioxidant screening methods for the assessment of their potency using Ascorbic acid as the standard drug. Antioxidant screening in-vitro methods used are such as Superoxide radical scavenging activity, Reducing power method, Phosphomolybdenum method, Ferric thiocyanate method, Thiobarbituric acid method, β-Carotene linoleic acid method/conjugated diene assay, and Fenton's reagent method. Different concentrations of test drugs were made and antioxidant activity was calculated by estimating inhibition percentage and IC50 values which were consequently compared with standard drug. The entire test drug RK, KH, RRH, and RRK showed relatively better antioxidant competence with that of the standard drug. Based on the above estimations, KH and RRH could be considered as the best potent drug for the diverse formulations of antioxidant effect suitable for the avoidance of various human diseases.
