Abstract

This study explains the controversies in the literature concerning the number of electrons involved in the oxidation of quercetin. This stems from inappropriate handling samples, which require strict anaerobic conditions. The redox potential of quercetin strongly depends on the pH and on the presence of dissociation forms in solution.

摘要

本研究解释了文献中关于槲皮素氧化涉及的电子数的争议。这源于对需要严格厌氧条件的样品处理不当。槲皮素的氧化还原电位强烈依赖于 pH 值和溶液中离解形式的存在。
