dc.description.abstractIn this study, antioxidant activities of two macroalgae, Eucheuma sp. J.Agardh and Laminaria sp.,J.V.Lamouroux used as food supplements were investigated. The antioxidant activity, free radicalscavenging activity, the total content of phenolics, flavonoids and condensed tannins in extracts weredetermined. The IC50 values of the extracts of Eucheuma sp. and Laminaria sp. on DPPH scavengingactivity was 2.26±0.03 mg/g and 2.63±0.03 mg/g of extract, respectively. The maximum totalphenolic (5.31±0.04 mg GAE/g Ext.) were determined. According to our results, all extractsexhibited low radical scavenging activity when compared to the standards used, i.e. ?-tocopheroland butylated hydroxytoluene (BHT) with the inhibition percentage in the range of 48.45±0.06%(Eucheuma sp.) – 58.49±0.03% (Laminaria sp.). The highest flavonoid content was measured as18.78±0.10 mg rutin/g of extract in Laminaria sp. The condensed tannins were not detected inEucheuma sp. However, this value was measured as 6.24±0.60 mg CE/g of extract for Laminariasp. According to our results, Eucheuma sp. and Laminaria sp., which are commercially sold inmedicinal herb stores, are good sources of antioxidant components because of their phenolic andflavonoid contents.
