“…Superoxide radicals were generated by pyrogallic acid method with some modification [12][13][14]. The reaction mixture contained 2 mL sample (0.0 -1 mg/mL) dis-solved in 2.25 mL Tris-HCl buffer (0.05 M, pH 8.0).…”

In the present study, olive leaf extract, harvested from four seasons, extracted with solvent (methanol and water), was treated by D101 and Sephadex LH-20, and divided into 10 fractions by TLC detection. The antioxidant activity was evaluated using DPPH, superoxide anion scavenging and reducing power assays. Tyrosinase inhibitory activity was also performed with L-DOPA as substrate. On extraction method, there is no significant difference in methanol and water. Among 12 months, autumn showed the best harvest time in whole. OLE showed 90% tyrosinase inhibitory activity and inhibition type was non-competitive competition. By chromagraphy treatment, the ingredients of polysacchmaride and protein showed high bioactivity towards antioxidant and anti-tyrosinase activity, the rest part showed different extent of activity and prove some effect by chromatography treatment indirectly. OLE might be a valuable bioactive source and can be applicable in both the cosmetic and medical use.

“…The reducing power of extracts was determined according to the Method described before [11,13,15,16] with slight modification. A 1 mL of extract sample or standard antioxidant (ascorbic acid) was mixed with 2.5 mL of 0.2 M phosphate buffer saline (pH 6.6) and 2.5 mL of 1% (w/v) potassium ferricyanide [K 3 Fe(CN) 6 ].…”

“…Extracts with higher electron donating activity can terminate the radical chain and turn free radicals into more stable products (Pan et al 2011). The extracts in the present study were shown to have considerable amounts of phenolic compounds that can donate electrons.…”

Green tea (Camellia sinensis), rosemary (Rosmarinus officinalis) and oak fruit (Quercus branti) are of known medicinal plants used in traditional medicine. They provide substantial antioxidant activities but the possible antioxidant interaction between them has not been studied. In the present study first the bioactive compounds from these three plants were first extracted and thereafter assayed for total phenols, 2, 2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, total antioxidant capacity (TAOC) and reducing power. In addition, the antioxidant properties of the extracts individually and in combinations were evaluated in soy bean oil as food system. There was a direct relation between total phenolics and antioxidant activities of extracts. Green tea and oak fruit extracts had the highest and least activity, respectively. All three kinds of interactions (synergistic, antagonistic and additive) were observed. In soy bean oil, the only effect was antagonism but even with this effect, combined extract was significantly (P<0.05) better than butylated hydroxytoluene (BHT) and control sample. Results showed that these three natural extracts and their combination can be effectively used as a substituent of synthetic antioxidant BHT.

“…There was no significant difference in the reducing power between DH-10 and DH-20. However, the reducing power of GSH with DH of 5-20 % at 6 mg mL −1 was in the range of 0.77-1.17, which is higher than that of some plant protein hydrolysates (Li et al 2008;Pan et al 2011). The results showed that GSH is a good electron donor and inhibits free radicals, indicating that it has strong potential for use as a natural antioxidant.…”

To observe the neuroprotective and antioxidant activities of the grass carp protein hydrolysates (GPH) obtained from grass carp (Ctenopharyngodon idella) skin by enzymatic hydrolysis. GPH prepared using Protamex, at different (5, 10, 15, 20 and 30 %) degrees of hydrolysis (DH) were investigated. The DPPH radial scavenging, reducing power and inhibition of linoleic acid oxidation activities of GPH were significantly improved by a low DH (5 %) compared with those of GPH with a higher DH (p<0.05). A low degree of enzymatic hydrolysis was appropriate to obtain GPH with improved neuroprotective activities. These results suggest that the control of the DH may be an effective strategy to modify specific neuroprotective and antioxidant activities of GPH, and GPH has potential as a functional food ingredient for related functional and health benefits.
