“…Phenolic content generally correlates with antioxidant capacities measured by DPPH or ABTS methods (Tabart et al 2009). Other studies indicate that the DPPH assay effectively determines the most reactive antioxidant components (Kim et al 2002), whereas the ABTS* assay measures the antioxidant activity of a wider range of polyphenolic compounds (Re et al 1999).…”

It was hypothesized that dietary polyphenol-rich fruit pomaces can improve the antioxidant status of both diets and the tissues of turkeys fed such diets. Turkeys were fed diets containing a cellulose preparation (C) or 5% dried apple pomace (AP), blackcurrant pomace (BCP), strawberry pomace (SP) and seedless strawberry pomace (SSP). Blood and liver biochemical parameters were determined in 7 birds from each experimental group slaughtered at 15 weeks of age, after 5 weeks of feeding diets containing soybean oil and linseed oil (approx. 1:1 ratio). Dietary linseed oil added to diets at 2.5% lowered the n-6/n-3 PUFA ratio from approx. 7:1 to below 2:1, thus reducing the antioxidant properties of diets measured using DPPH, ABTS and photo-chemiluminescence assays, compared with diets containing only soybean oil and administered to birds in the first phase of feeding. Fruit pomaces, in particular SSP with the highest polyphenol content (32.81 g/kg) and the highest antioxidant activity (256.4 μM Trolox/g), increased the antioxidant capacity of turkey diets. In comparison with the control group, the dietary treatments with fruit pomaces improved blood antioxidant parameters, including catalase activity (groups AP and BCP), the total antioxidant capacity of hydrophilic (group AP) and lipophilic (groups AP, SP, and SSP) compounds, peroxide levels (groups AP and SSP) and antioxidant capacity measured by the FRAP (ferric reducing antioxidant power of plasma) assay (groups AP, BCP and SSP). Significantly lower concentrations of both vitamin E and thiobarbituric acid reactive substances (TBARS) were noted in the livers of turkeys fed all diets with dried fruit pomaces.

The present study evaluates the antioxidant activity of two Aronia melanocarpa cultivars-Viking and Aronand of Aronia prunifolia hybrid in relationship with their phytochemical composition regarding the contents of total phenolics, flavonoids, procyanidins, and monomeric anthocyanins. The antioxidant capacity of the mentioned extracts of chokeberries was evaluated through five complementary assays: 2,2 0 -azino-bis(3-ethylbenzothiazoline-6-sulfonic acid), H2O2 scavenging potential, oxygen radical absorbance capacity, ferric reducing antioxidant power, and cupric ion reducing antioxidant capacity. A. prunifolia hybrid was found to have the highest antioxidant activity and to be the richest in polyphenols, procyanidins, and anthocyanins compared with the A. melanocarpa cultivars. A good correlation was observed between antioxidant activity and total procyanidin and anthocyanin content. Cyanidin glycosides inhibited HeLa human cervical tumor cell proliferation and increased generation of reactive oxygen species after 48 h of treatment, suggesting that they could be responsible for the antiproliferative activity. These results may be significant for industry concerning food quality and disease prevention.

“…The majority of authors evaluated DPPH activity via evaluation of EC 50 (the sample concentration necessary to reduce the initial DPPH activity to 50%), or percentage inhibition (%). DPPH has been widely used for free radical-scavenging assessments due to its simplicity and convenience.…”

“…Because the antioxidant activity measured by an individual assay reflects only the chemical reactivity under the specific conditions applied in that assay, as pointed out by many authors [48][49][50][51][52], it is inappropriate and misleading to generalize the data obtained by a single method as indicators of antioxidant activity. There are no standardized assays for determining antioxidant capacity of any sample, and their "importance" or usefulness depends exclusively on the mechanism of action of antioxidants expected to be found in the particular sample.…”

-Introduction. Deciduous tree fruits like peach (Prunus persica (L.) Batsch var. persica), nectarine (Prunus persica (L.) Batsch var. nucipersica (Suckow) C.K.Schneid), and especialy plum (Prunus domestica L. ssp. domestica) are very common in Serbia. These fruits are known for their nutritional value and therapeutic properties and are valuable sources of antioxidants. Materials and methods. The goal of this work was to evaluate fruit tissue antioxidant activity using methanol extracts of 9 peach, 3 nectarine and 7 plum cultivars. The following parameters were measured: total phenolic content (TPC); antioxidant activity as estimated by radical scavenging activity of (2,2-diphenyl-1-picrylhydrazyl, DPPH); cation decolorization activity (2,2-azinobis-3 ethylbenxothiazoline-6-sulphonic acid, ABTS); ferric reducing antioxidant power (FRAP); cupric reducing antioxidant capacity (CUPRAC); and total reducing power (TRP). Results and discussion. Total phenolic contents of the plum cultivars were higher than those of peach and nectarine and significant positive correlations were recorded between all antioxidant activity assays and total phenolic contents. Results obtained by principal component analysis (PCA) are in agreement with those obtained by cluster analysis (CA). Conclusion. The selected methods revealed antioxidant activities for all plum cultivars significantly higher than in the peach and nectarine cultivars. PCA and CA allow grouping the different fruit species based on TPC, DPPH, ABTS, TRP, FRAP and CUPRAC values.
