Iron-induced peroxidation of trilinolein nano-emulsions under model gastric conditions and its inhibition by dietary phenolic antioxidants

An early mechanism for the health benefits of dietary plant phenols is their antioxidant activity during the initial phase of gastric digestion.

Synergy between plant phenols and carotenoids in stabilizing lipid-bilayer membranes of giant unilamellar vesicles against oxidative destruction

The synergistic antioxidant effect of plant phenols and carotenoids at the lipid–water interface was consistent with the Marcus theory.

The Use of X-Ray Fluorescence Analysis Using Synchrotron Radiation to Study the Relationship between Chemical Elements and Phenolic Compounds in the Blue Honeysuckle Plants

Macro- and trace elements variation limits in the blue honeysuckle leaves, collected in the geochemically contrasting environments in the Altai Mountains, were determined by X-ray fluorescence analysis using synchrotron radiation, and their relationship with plant secondary metabolism analyzed. In content of main classes of biologically active plant phenols were found in habitats with increased Ca and Sr contents, resulting in decreased soil K/Ca ratio. The same habitats were found to have increased Cu/Zn and Fe/Zn ratios and decreased Fe/Cu and Fe/Ni ratios.

Effect of soybean plant phenols and flavonoid on the mean leaf area consumed by Spodopteralitura and Spilosoma obliqua larvae

The aim of the present investigation was to study the effect of soybean plant phenols and flavonoid content on the mean leaf area consumed by Spodopteralitura and Spilosoma obliqua larva. Phenols and flavonoid content in methanolic leaf extract of thirty three genotypes of soybean were determined by spectrophotometrically. Thehighest and lowest phenolic content were found in genotypes JS-20-41(2.2±0.073 mg/g) and CSB 904 (0.45 ±0.11 mg/g), respectively. While the highest and lowest flavonoid content was found in genotypes SL 979 4.686± 0.062 mg QE/ g, respectively. In correlation study a highly significant negative correlation was observed between mean leaf area consumed (cm2) by S. litura, phenol content (-0.741 ) and flavonoid content (-0.737) similarly a highly significant negative correlation was observed between mean leaf area consumed by S. obliqua, phenol content (-0.728) and flavonoid content (-0.736) in leaves. Hence it can be concluded that, the genotypes which were having higher phenol and flavonoid content in their leaves offered resistance against S. litura and S. boliqua in soybean.
