The phenolic compounds, antioxidant activity and neuronal cell protective effect of Cirsium japonicum extract were evaluated in this study. High performance liquid chromatography mass analysis showed that C. japonicum was composed of chlorogenic acid, linarin, and pectolinarin. C. japonicum extract showed its antioxidant activity with halfmaximal inhibitory concentrations of 567 and 130 µg/mL by DPPH and ABTS radical scavenging activity, respectively. The total antioxidant capacities of C. japonicum via DPPH, ABTS, and FRAP assays were 11.32, 100.15, and 12.76 µg/ mL trolox equivalents, respectively. In addition, the neuroprotective effect of C. japonicum extract was investigated by measuring cell viability via MTT, LDH and DCF-DA assay using H 2 O 2 -damaged PC12 cells. C. japonicum extract showed neuronal cell protective effects in a dose-dependent manner. These results indicated that C. japonicum extract has potent antioxidant and neuronal protective effects. Therefore, C. japonicum can be regarded as an effective and safe functional food resource as natural antioxidants, and may decrease the risk of neurodegenerative disorders.

“…Dinis et al (2012) ascribed the DPPH and ABTS + radical scavenging activities of chestnuts to the presence of polyphenolics, which explains the ABTS + radical scavenging activity trend observed herein. Jang et al (2012) observed a positive correlation between DPPH/ABTS + radical scavenging activities and polyphenol content, which implies a correlation between the two activities. The reducing power of the control, 2.5%, 5%, 7.5%, and 10% groups was 0.01, 0.75, 0.94, 1.15, and 1.33, respectively, i.e., increased with the increasing chestnut powder content (p<0.001; Fig.…”

This study examined the effects of chestnut powder content (2.5%, 5%, 7.5%, and 10%) on the antioxidant activity and quality characteristics of rice muffins. With the increasing chestnut powder content, the total polyphenol content, flavonoid content, antioxidant activity (determined by radical scavenging activity and reducing power), hardness, gumminess, chewiness, and overall acceptability (determined by sensory evaluation) increased, whereas the moisture content, pH, specific volume, and cooking loss decreased. Regarding color, chestnut powder content was negatively correlated with L and b and positively correlated with a. Notably, overall acceptability abruptly decreased to its minimum at 10%. Thus, adding powder at loadings of <7.5% improved the antioxidant activity and acceptability of rice muffins. Our results can be used as preparatory data for developing a rice muffin model.

In this study, the antioxidant effect of water and ethanol extracts from Juniperus rigida Sieb were investigated. The activities of each of the extracts were measured based on their total phenolic and flavonoid contents and using antioxidant test such as of 2,2-azinobis (3-ethyl benzothiazoline-6-sulfonic acid (ABTs) radical scavenging activities, ferric reducing antioxidant power (FRAP), angiotensin I converting enzyme (ACE) inhibition activity, antioxidant protection fator (PF), thiobarbituric acid reactive substances (TBARs) content, and α-glucosidase and α-amylase inhibition activity assay. The result of the examination to measure the polyphenol content by investigating the antioxidativity of the J. rigida Sieb. extract showed 71.3 mg/g polyphenol content in the water extract, and 116.0 mg/g in the ethanol extract and a 17.7 mg/g flavonoid content in the water extract and in 76.4 mg/g in the ethanol extract. The ABTS radical cation decolorization showed 76.4% and 79.3% scavenging activities of the 500 µg/mL water extract and ethanol extract, respectively. The FRAP showed 1.83 mM efficacy in the water extract and a lower 1.77 mM in ethanol extract. Both the water extract and the ethanol extract showed reduced ACE activities of 75.39% and 71.25% at 500 µg/mL, respectively. The antioxidant protection factor of the water and 70% ethanol extracts of J. rigida Sieb were 1.5 PF and 2.1 PF, respectively. In the TBARS inhibitory activity, the extracts showed 55.78% and 71.48% antioxidant activities at the 500 µg/mL concentration. The results of the measurrement of the α-amylase inhibitory activity indicated more than 90% of activity inhibition in the 500 µg/mL concentration of the ethanol extract. For the α-glucosidase inhibitory activity, the ethanol extract showed 70% activity inhibition at the 500 µg/mL concentration.
