摘 要:目的:合成出聚氧化乙烯基-β-环糊精,并测定其溶血作用和槲皮素的增溶作用。方法:β-环糊精在碱溶液中与环氧乙烷反应生成聚氧化乙烯基-β-环糊精,用红外光谱、核磁共振波谱等方法鉴定合成的产物;用兔全血中分离的血红细胞测定其在体外的溶血作用;用紫外分光光度法测定其对槲皮素的增溶作用。结果:聚氧化乙烯基-β-环糊精溶血作用不仅比β-环糊精显著降低,也明显低于羟丙基-β-环糊精;且对槲皮素的增溶作用显著。结论:聚氧化乙烯基-β-环糊精是一种极具应用潜力的药用辅料。Objective: To synthesize polyoxyethylene-β-cyclodextrin (PE-β-CD) and study its hemolysis in vitro and its effect on the solubilization of quercetin in water. Methods: β-cyclodextrin was used to react on epoxy ethane in alkali solution to obtain polyoxyethylene-β-cyclodextrin which was identified by IR spectrophotometry and ^13C-NMR spectral analysis. The hemolysis was deteated by means of red blood cells isolated from whole rabbit blood and the effect of PE-β-CD on solubilization of quercetin in water was studied by UV spectrophotometry. Result: The hemolytic potential of PE-β-CD was much smaller than that of β-CD, and also smaller than that of HP-β-CD. PE-β-CD also exhibited a remarkable effect on solubilization of quercetin in water. Conclusion: PE-β-CD may well be applied as a novel auxiliary material for injection.
