Hydrolysable tannins occur in plants that are used for food or medicine by humans or herbivores. Basic conditions can alter the structures of tannins, that is, the oxidation of phenolic groups can lead to the formation of toxic quinones. Previously, these labile quinones and other oxidation products have been studied with colorimetric or electron paramagnetic resonance methods, which give limited information
可水解的丹宁酸存在于人类或食草动物用于食品或药品的植物中。碱性条件会改变单宁的结构,即酚基的氧化会导致有毒醌的形成。以前,已经用比色法或电子顺磁共振法研究了这些不稳定的醌类和其他氧化产物,这些方法只能提供有关产物的有限信息。
