用荧光光谱技术确定了β-环糊精(β-CD)与阿霉素(ADM)之间的超分子包络物ADM-β-CD的形成.研究了时间、浓度和温度对包络反应的影响,确定了包络物形成的化学计量比,计算了在不同温度下的包络常数和包络反应的热力学参数.在33℃、pH=7.0时,包络常数K=2.98×106 L/mol,且包络常数随温度升高而变小,该包络反应属于焓驱动的自发的放热反应.由于β-CD对ADM的天然荧光有增强作用,因此,ADM与β-CD形成超分子包络物后,荧光强度增大,荧光光谱是研究ADM与β-CD超分子包络反应的很好的技术.求得β-CD增敏荧光法定量测定ADM的线性回归方程为:F=5.64×108c+47.26,相关系数r=0.9985,检测下限为6.30×10-8mol/L.
