Objective:To assess in-vitro antioxidant activity of different fraction and perform high performance thin layer chromatography fingerprint analysis of most active fraction of Rumex vesicarius L.(***).Methods:In the present study,acetone,ethyl acetate,n-butanol,and methanol extracts of *** were evaluated for radical scavenging activity by studying the inhibition of the level of lipid peroxidation induced by Fe(++)/ascorbate,DNA sugar damage,scavenging of hydrogen peroxide,diphenylphosphine DPPH radical scavenging activity,total phenolic content,total flavonoids content and total *** performance thin layer chromatography finger print profiling of *** *** also ***:Lipid peroxidation induced by the iron/ascorbate system,hydrogen peroxide,diphenylphosphine and DNA sugar damage were inhibited by the addition of different extract of *** them,methanolic extract showed maximum *** methanolic extract showed the highest total phenolic,total flavonoids and total proanthocyanidin ***:The results suggest that the extracts can be a vital source of phytochemical antioxidants.
