The antioxidant capacity indicates the degree of protection of a certain organism against oxidative damage provoked by reactive oxygen and nitrogen species. These methods were applied to a number of commercial fruits and blackberry herbal tea. The findings of cupric ion reducing antioxidant capacity method are statistically compared to those of the ceric-reducing antioxidant capacity method, which is a relatively. new one. In addition to this, we were also investigated the kinetic degradation of the ascorbic acid in a certain type of fruit juice.eninfo:eu-repo/semantics/closedAccessAscorbic acidCeric-reducing antioxidant capacityCupric ion reducing antioxidant capacityAntioxidantKineticsTotal Antioxidant CapacityDehydroascorbic AcidOxidative StressSpectrophotometric DeterminationFree-RadicalsVitamin-CAccumulationTransportArticle24626092612Q4WOS:0003050339000512-s2.0-84861672712Q4
