使用紫外-可见分光光度法，我们已经确定在花青素分子，马来素氯（马来素3,5-二葡糖苷）和非糖化的五羟基黄酮，槲皮素（3,5,7,3',4'-五羟基黄酮）之间发生了共色素化过程。表征该过程的动力学和热力学参数与结构有关，即相互作用分子中取代基的性质和位置。
Using UV-vis spectrophotometry we have established that a process of copigmentation takes place between an anthocyan molecule, malvin chloride (malvidin 3,5-diglucoside), and a nonglycosidized pentahydroxyflavone, quercetin (3,5,7,3',4'-pentahydroxyflavone). The kinetic and thermodynamic parameters, by which the process is characterized, were correlated to the structure, i.e., the nature and position of the substituents in the interacting molecules.
