DPPH molecule that contains a stable free radical has been widely use to evaluate the radical scavenging ability of antioxidants. From Table 1, results showed that DPPH radical scavenging abilities of the extract is less than that of ascorbic acid C. afer (IC 50 = 1.09 ± 0.02 mg/g) > ascorbic acid (IC 50 = 0.008147 ± 4.18×10 −5 mg/g).

Background The aim of the present study was to evaluate the in vitro antioxidant and free radical scavenging capacity of bioactive metabolites present in Newbouldia laevis leaf extract. Results Chromatographic and spectrophotometric methods were used in the study and modified where necessary in the study. Bioactivity of the extract was determined at 10 μg/ml, 50 μg/ml, 100 μg/ml, 200 μg/ml

Background In humans, many diseases are associated with the accumulation of free radicals. Antioxidants can scavenge free radicals and minimize their impact. Therefore, the search for naturally occurring antioxidants of plant origin is imperative. Here, we aimed to investigate the antioxidant and free radical scavenging properties of methanolic extracts from Tabebuia pallida (T. pallida) stem

Results. EGT was the most active scavenger of free radicals as compared to classic antioxidants as GSH, uric acid and trolox. In particular, the highest antioxidant capacity exhibited by EGT vs. peroxyl radicals (5.53 ± 1.27 units) resulted 25% higher than the value obtained with the reference antioxidant trolox (4.4 ± 0.6 units, P < 0.01).

Divergent literature data are found concerning the effect of lactate on free radical production during exercise. To clarify this point, we tested the pro- or antioxidant effect of lactate ion in vitro at different concentrations using three methods:1) electron paramagnetic resonance (EPR) was used to study the scavenging ability of lactate toward the superoxide aion (O2 −·) and hydroxyl

The non-sugar part of saponins has a direct antioxidant activity which may contribute to the high free radical scavenging capacity of the plant leaf extract. The trace level of cyanogenic glycoside could suggest the plant's very low toxicity when ingested in the form of traditional medicine ( Table 1 ).

Highlights A method for the assessment of antioxidant capacity for radical scavenging was developed. The reactivity and concentration of antioxidants in mixtures were measured separately. Probes with various reactivities and solubilities were used for the assessment. The effect of localization of radicals and antioxidants in water and oil phases was assessed. The method was applied to human
