Abstract: The present study was aimed to explore the antioxidant potential of Thenus unimaculatus extract by methanolic and chloroform. The yield was calculated, and the maximum was found in chloroform 49% followed by methanol 45%. The DPPH radical scavenging effect has showed concentration depended and the results have been recorded 13, 21, 33, 41 and 54% in methanol and 4, 6, 11, 19 and 24% in chloroform at the concentration of 1-3mg/ml. The ferrous ion chelating ability of Thenus unimaculatus methanolic and chloroform extracts has showed dose depended and the result has shown in Fig.2. The methanolic extract has showed 14, 28, 37, 53 and 69% and the chloroform extract has showed 6, 13, 21, 30 and 42%. The hydroxyl radicals scavenging effect of methanolic extract has showed 3, 7, 11, 16 and 29 % and the chloroform extract has showed 14, 26, 34, 48 and 61%. Methanolic extract has showed potential antioxidant radicals scavenging metabolites and it’s an alternate source for development of drug in pharmaceutical industry.
