| 摘 要： | 研究发现,在六次甲基四铵-盐酸缓冲溶液中,阴离子表面活性剂十二烷基苯磺酸钠与阳离子表面活性剂十六烷基三甲基溴化铵形成的混合胶束对槲皮素的荧光强度有明显的增强作用。利用荧光光谱、共振光散射光谱、紫外吸收光谱研究了混合胶束对槲皮素的荧光增强机理。结果发现,混合胶束能为槲皮素提供更好的疏水环境,使槲皮素的吸收增强,进而使槲皮素的荧光增强。

| Abstract: | It was found that in a hexamine-HCl buffer solution,the mixed micelle of anionic surfactant sodium dodecyl benzene sulfonate and cationic surfactant hexadecyl trimethyl ammonium bromide could enhance the fluorescence intensity of quercetin.Under optimal conditions,the interaction of quercetin with mixed micelle was studied quantitatively by fluorescence spectroscopy,resonance light scattering spectrophotometry and ultraviolet-visible spectroscopy.It was considered that the mixed micelle provided an optimum hydrophobic environment with low polarity that could enhance the fluorescence intensity of quercetin. |
