  "abstract": "<p>The antioxidant potential and total phenolic contents of a red alga&nbsp;<em>Agardhiella robusta&nbsp;</em>(Grevi.) Borg belonging to Rhodophycota&nbsp; collected from coastal areas of&nbsp; Karachi, Pakistan was investigated through various in vitro protocols. Antioxidant potential measured through total antioxidant determination, total phenolic contents, ferric reducing antioxidant power (FRAP) and DPPH analysis. The antioxidant components were initially extracted in methanol and were further fractionated in solvents of different polarity. The results showed that the petroleum ether fraction exhibited highest DPPH radical scavenging activity, i.e. (79.5&plusmn;1.9%) at a concentration of 1000ug/ml with IC50 286.13&plusmn;0.34 &micro;g/mL relative to the BHT. While Methanol extract showed highest &nbsp;phenolic contents i.e. 1542.5 &plusmn;1.2 GAEmg/mL, highest FRAP values i.e. 18.95&plusmn; TEuM/mL as well as least IC50 value of 25.81 &plusmn; 0.65 &mu;g/mL which indicated its potential for scavenging the free radicals. On the basis of these results obtained here&nbsp;<em>Agardhiella robusta&nbsp;</em>(Grevi.) Borg considered as a rich source of&nbsp; antioxidant.</p>",
