摘 要:以包合率为指标,优化了芹菜素磺丁基醚-β-环糊精包合物的制备方法及工艺参数。结果表明,采用研磨法将芹菜素与磺丁基醚-β-环糊精(投料摩尔比1∶5)研磨1.5 h,可制得包合率为79.5%的包合物。运用相溶解度法考察25、37和50℃时磺丁基醚-β-环糊精对芹菜素的增溶作用,结果表明芹菜素的表观溶解度随温度的上升和磺丁基醚-β-环糊精浓度的增大而显著增大,且包合过程为自发过程。差示扫描量热和红外光谱分析结果表明,磺丁基醚-β-环糊精能与芹菜素形成较稳定的包合物。The preparation methods of inclusion complexes between apigenin and sulfobutyl ether β-cyclodextrin (SBE-β-CD) as well as the process parameters were optimized with inclusion rate as index. The optimal product with inclusion rate of 79.5 % was prepared by grinding method with molar ratio of 1 : 5 (apigenin to SBE-β-CD) and grinding time of 1.5 h. The solubilization effect of SBE-β-CD on apigenin at 25, 37 and 50 ℃ were investigated by phase solubility method. The results showed that the apparent solubility of apigenin was significantly increased with the increasing of temperature and SBE-β-CD concentration, and the inclusion process was spontaneous. The results of DSC and FT-IR analyses showed that a rather stable inclusion complexes had been formed.
关 键 词:芹菜素 磺丁基醚-Β-环糊精 包合物 溶解度 增溶
