Soybean plant responses to Heterodera glycines (H. glycines) race 3 infection were compared between resistant (Peking, LiaoK89102 and Franklin) and susceptible cultivars (Liao dou 10 and Kaiyu 10) at 10, 17, 20, and 23 days after inoculation (DAI). After inoculation with H. glycines race 3, the isozymes of peroxidase, polyphenol oxidase, superoxide dismutase, and catalase from the soybean roots...

OBJECTIVE The aim of this study was to estimate the intake of known individual polyphenols and their major dietary sources in the Polish arm of the HAPIEE (Health, Alcohol and Psychosocial factors In Eastern Europe) study. METHODS A total of 10,477 random sample (45-69 y) of urban population of Krakow, Poland, completed a validated 148-item food frequency questionnaire. Polyphenol intake was ...

BACKGROUND To identify associations between polyphenol intake and health and disease outcomes in cohort studies, it is important to identify biomarkers of intake for the various compounds commonly consumed as part of the diet. OBJECTIVE The objective of this systematic review was to assess the usefulness of polyphenol metabolites excreted in urine as biomarkers of polyphenol intake in humans....

The aim of this study was to examine the possible antioxidant activities of the methanol and water extracts of 31 medicinal wetland plants in Taiwan. We assayed for such properties such as: TEAC, DPPH radical scavenging, total polyphenol content, total flavonoid and total flavonol contents using the reducing power method. Our results showed that Rotala rotundifolia, Juncus effusus var. decipien...

in this study extract of olive leaf was added to butter samples at three concentrations, 0.05, 0.1 and 0.5% and after vaccum packaging, were kept in refrigerator for 90 days. acid and peroxide value, microbial culture , polyphenol content of samples ,hardness, oxidative stability, sensory characteristics of samples including flavor, textural and apparent characteristics of samples and dpph radi...

Polyphenol oxidase is the popular enzyme involved in fruit-vegetable browning and melanin synthesis. In present paper, L-3-phenyllactic acid, a natural bacteriostatic substance, was investigated as an inhibitor of polyphenol oxidase. The results were demonstrated that residual activity decreased gradually with increase concentration acid. L ΔE values reaction system increased gradually. reversi...

Tea (Camellia sinensis) is a widely consumed beverage and recognised for its potential enhancing effect on human health due to its rich polyphenol content. While a number of studies have investigated the quantity and type of polyphenols present in different tea samples, no study has reported the potential effect of digestive enzymes on the availability of tea polyphenols for human absorption or...
