摘要
目的:研究羟丙基-β-环糊精在水溶液中对甲砜霉素的包合作用。方法:采用相溶解度法考察甲砜霉素与羟丙基-β-环糊精在水溶液中包合作用、包合比及包合过程中的热力学参数变化。结果:在不同温度(25℃、35℃、45℃)下,甲砜霉素的溶解度均随羟丙基-β-环糊精溶液浓度的增加而呈线性增加,相溶解度图为AL型。结论:在上述研究条件下,甲砜霉素与羟丙基--β环糊精可自发地形成摩尔比1:1的包合物。
Objective:To investigate the complexation of thiamphenicol with hydroxypropyl-β-cyclodextrin (HP-β-CD) in aqueous solutions. METHODS: The complexation of thiamphenicol with HP-β-CD, the inclusion molar ratio of host and vip molecules and thermodynamic parameters were detected using phase solubility method. RESULTS: The solubility of thiarnphenicol increased linearly with the increase of HP-β-CD level in aqueous solutions at different temperatures (25℃,35℃ and 45℃),the phase solubility diagram was classified as type AL. CONCLUSIONS: Under the above research condition, the inclusion complexes of thiamphenicol with HP-β-CD can be formed spontaneously at a molar ratio of 1:1.
