Bioactive properties of laminarin and fucoidan samples in different antioxidant assays. (a) 1,1-diphenyl-2-picryl-hydrazyl (DPPH) activity and (b) ferric-reducing antioxidant power (FRAP) assays at different concentrations. The graph shows the sample concentration in µg/mL on the X-axis and the percentage inhibition of antioxidant values on the Y-axis. All values represent the means of triplicate results (n = 3, Mean ± S.D.). Significant statistical differences in the antioxidant potential are represented as * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001. The seaweed samples used for the study were crude laminarin (C.L.), an MWCO 10 kDa laminarin fraction (M.L.), a Sigma laminarin standard (S.L.), crude fucoidan (C.F.), an MWCO 10 kDa fucoidan fraction (M.F.), and a Sigma fucoidan standard (S.F).
