Our research intended to explore the antioxidant potential of fish protein hydrolysates of <em>Anguilla anguilla</em>&nbsp;and&nbsp;<em>Brachirus orientalis</em>. The mucus extracts of the marine fishes were determined for their antioxidant activities such as DPPH radical scavenging activities, Nitric oxide radical inhibition assay (NO&deg;), Hydrogen peroxide radical inhibition assay (H2O2), Superoxide radical inhibition assay (O2-), Assay for&nbsp;<em>in vitro&nbsp;</em>Ferric Reducing Antioxidant Power (FRAP assay) and Reducing power. <em>Brachirus orientalis&nbsp;</em>showed maximum percentage of activity against DPPH radical scavenging (</span></span></span></span><span style="font-size:12.0pt"><span style="line-height:120%"><span new="" roman="" style="font-family:" times="">62.12&plusmn;0.51<span style="color:#0e101a">) and Nitric oxide radical inhibition assay (NO&deg;) (</span>61.12&plusmn;0.31<span style="color:#0e101a">) compare to that of Anguilla<em> Anguilla, Whereas</em> the<em>&nbsp;</em>FRAP assay (</span>59.22&plusmn;0.43<span style="color:#0e101a">), Hydrogen peroxide radical inhibition assay (H2O2) (</span>66.41&plusmn;0.24<span style="color:#0e101a">), and reducing power assay (</span>1.64&plusmn;0.24<span style="color:#0e101a">) in&nbsp;<em>Anguilla anguilla&nbsp;shows maximum activity </em>compare to that of <em>Brachirus orientalis</em>. The Superoxide radical inhibition assay (O2-) was recorded same in both the fish species. This study indicates that the epidermal mucus of&nbsp;<em>Anguilla anguilla</em>&nbsp;and&nbsp;<em>Brachirus orientalis</em>&nbsp;pave way to develop novel natural antioxidants or new therapeutic agents.</span></span></span></span></span></span></span><br> &nbsp; Anguilla anguilla, Brachirus orientalis, Nitric oxide assay, DPPH, Reducing power assay 27 38 http://injvr.com/browse.php?a_code=A-10-1-6&slc_lang=fa&sid=1 G.
