The antioxidant potential of a new water soluble flavonic derivative, namely theophylline rutoside (TR-1722) has been tested using the chemiluminescence method. The method is based on the oxidative degradation of luminol by the hydrogen peroxide in Tris-HCl-buffer, when reactive species of oxygen are being obtained: O2-., HO., 1O2, and allows for the capability of substances to inhibit the free radical processes in this test system to be quantified and hence for their antioxidant properties in… Expand
Oxidation of the flavonol quercetin by polyphenol oxidase.
TLDR
Results obtained showed that quercetin oxidation was strictly dependent on the presence of PPO, and was efficiently inhibited by specific PPO inhibitors such as 4-hexylresorcinol. Expand
