摘要: 研究了β-环糊精(β-CD)对胆固醇的增溶,结果表明增溶系数(St/S0)可达到最大值(约1.8)。在达到最大增溶之前,β-CD和胆固醇可形成稳定的2∶1包合物。根据主客体分子的极性和尺寸的匹配性,推断了β-CD与胆固醇包合物的可能构象。

Abstract: The solubilization of cholesterol by β-cyclodextrin(β-CD)in apueous solution was investigated in this paper.The results showed that the solubilization coefficient(St/S0)of cholesterol had a maximal value(about 1.8).By means of linear regression,it was demonstrated that β-CD with cholesterol could form stable ratio of 2∶1 inclusion complex in aqueous solution before maximal solubilization.Accoding to the molecular size-match and polarity the possible, configuration of 2∶1 inclusion complex was envisaged.
