The interactions of flavonoid, quercetin with sodium dodecyl sulfate (anionic surfactant) and cetyltrimethyl ammonium bromide (cationic surfactant) micelles were investigated. The average location site of quercetin in different micelles was determined by the cyclic voltammetry method with the aid of molecular optimization. The interaction parameters of quercetin with micelles of different charges such as binding constant K and normal binding energy DeltaG were calculated. Furthermore, the morphologic change of the SDS and CTAB spherical micelles and rod-like micelles upon their interaction with quercetin was also observed.
研究了类黄酮槲皮素与十二烷基硫酸钠（阴离子表面活性剂）和十六烷基三甲基溴化铵（阳离子表面活性剂）胶束的相互作用。借助分子优化，通过循环伏安法确定了槲皮素在不同胶束中的平均定位位点。计算了槲皮素与不同电荷胶束的相互作用参数，如结合常数K和标准结合能ΔG。此外，还观察了SDS和CTAB球形胶束及棒状胶束与槲皮素相互作用后的形态变化。
