| 摘 要： | 用研磨法制备β-环糊精(β-CD)及羟丙基-β-环糊精(HP-β-CD)与鹰嘴豆异黄酮(CAI)的包合物,由红外吸收光谱对包合物进行表征,并运用紫外分光光度法测试包合体系吸光度的变化.根据Benesi-Hildebrand方程确定了包合反应的表观包合稳定常数Kfθ和包合反应的热力学参数ΔGθ,ΔHθ和ΔSθ,并由此得出包合反应主要由焓变控制,推动力为范德华力.

| Abstract: | The inclusion complexes of β-cyclodextrin(β-CD)and hydroxypropyl-β-cyclodextrin(HP-β-CD)with cicer arietinum isoflavones(CAI)were prepared by the grinding method and characterized by infrared absorption spectrum,the changes of absorbance were measured by UV absorption spectrum.The inclusion equilibrium constant(Kθf)of inclusion complex was determined by Benesi-Hildebrand equation and the thermodynamic parameters of the inclusion reaction,such as ΔGθ,ΔHθ and ΔSθ were obtained from the inclusion constants at different temperatures.The whole inclusion process was controlled mainly by enthalpy and driven by Van Der Waals Forces. |
