Figure 4.
Total soluble (a) and fat-soluble (b) antioxidant capacities determined in K. alvarezii and K. striatus. The data are represented as the mean ± SD (n = 36 for each year). The results were analyzed via Mann–Whitney U test: * significant difference (p < 0.05) of the soluble and fat-soluble antioxidants obtained via FRAP test compared to those determined via DPPH and ABTS assays in K. alvarezii; ** significant difference (p < 0.05) of the soluble and fat-soluble antioxidants obtained via FRAP test compared to those determined via DPPH and ABTS assays in K. striatus. No significant difference between the soluble and fat-soluble antioxidant capacity measured by the ABTS and DPPH assays is observable in either species.
