采用紫外分光光度法研究柠檬醛与 β-CD 衍生物的包合作用。通过正交试验优化山苍子精油-β-CD 包合物的制备工艺。柠檬醛与 β-CD 衍生物的包合比为1∶1,包合物的形成常数随温度的升高而减少。热力学参数(ΔH°,ΔG°,ΔS°)表明包合过程为自发放热过程,主要驱动力为焓变(ΔH°)。通过综合评分法优选的山苍子精油-β-CD包合物制备工艺是:油料比1∶6,包合温度30 ℃,包合时间1.5 h。IR,XRD和SEM 确证了包合物的形成。

Inclusion of citral with β-CD derivatives was studied by spectrophotometry, and inclusion process of Litsea cubeba oil-β-CD complex was optimized by orthogonal experiment. Stiochiometric ratio of citral-β-CD complex is 1:1, and formation constant of complex decrease with the increase of temperature. The thermodynamic parameters (ΔH°, AG°, AS°) showed that the complex formation is a spontaneous and exothermic process, and the main driving force is enthalpy. Preparation of Litsea Cubeba oil-β-CD complex was optimized by comprehensive eval...
