摘 要:目的:制备尼古丁羟丙基-β-环糊精(HP-β-CD)包合物,并进行包合物的稳定性考察。方法:采用冷冻干燥法制备尼古丁的包合物,通过星点设计-效应面法优化制备工艺,并做了热稳定性初步考察。结果:最佳的包合工艺为HP-β-CD与尼古丁物料摩尔比为3.36∶1,包合温度45℃,包合时间3.5 h,水与HP-β-CD摩尔比为20∶1,平均包合率为56.22%,与预测值吻合。尼古丁采用环糊精包合后稳定性有显著提升。结论:该模型预测下的优化工艺可行,可作为尼古丁包合物的制备工艺。OBJECTIVE To prepare inclusion complex of nicotine with HP-β-CD( nit-HP-β-CD),and study stability of inclusion complex. METHODS nit-HP-β-CD was prepared by freeze-drying method. Central composite design and response surface methodology were chosen to optimize process of preparation. Thermal stability was also primarily studied. RESULTS Optimum technological parameters were as follows: ratio of HP-β-CD / nit 3. 36∶ 1,reaction temperature was 45 ℃,ratio of water / HP-β-CD 20∶ 1,and reaction time was 3. 5 h. Inclusion rate was 56. 22%,which was close to predicted value. Nicotine had significantly improved stability after included by HP-β-CD. CONCLUSION Optimized process predicted in this model is feasible,and can be used as preparation process of nicotine.
