In Vitro Evaluation of Pro- and Antioxidant Effects of Flavonoid Tricetin in Comparison to Myricetin.

摘要: Flavonoids are rather common plant phenolic constituents that known for potent antioxidant effects and can be beneficial human health. with a pyrogallol moiety highly efficient reducing agents possible pro- effects, depending on the reaction milieu. Therefore, redox properties of myricetin tricetin were investigated by differential pulse voltammetry deoxyribose degradation assay. Tricetin proved to good but only showed negligible pro-oxidant activity in one assay variants. Compared tricetin, effects. The more probably caused positive mesomeric effect enolic 3-hydroxy group ring C. It is evident structurally similar flavonoids converted apparent relatively small structural changes, such as hydroxylation. Since reactive oxygen species (ROS) often serve secondary messengers pathological physiological processes animal cells, an important part controlling mechanisms tissue signal cascades.
