用紫外光谱法研究了系列β-环糊精衍生物(羟丙基-β-环糊精、羟乙基-β-环糊精和甲基-β-环糊精)对α-苯丙酸的包结作用,考察了不同β-环糊精衍生物对不同存在状态的α-苯丙酸的包结行为.结果说明,α-苯丙酸与β-环糊精衍生物形成的包合物的包合比为1:1,三种主体环糊精的包结能力强弱顺序为:羟乙基-β-环糊精＞羟丙基-β-环糊精＞甲基-β-环糊精,羟丙基-β-环糊精适合包结分子状态的α-苯丙酸,而不易包结离子状态的α-苯丙酸.

The inclusion of α-phenylpropionic acid(PPA)with β-cyclodextrin derivatives (HP-β-CD,HE-β-CD,Me-β-CD)in aqueous solution was studied by UV spectrometry.Effects of type of β-cyclodextrin derivative and presence state of PPA on inclusion were investigated.PPA and β-cyclodextrin derivatives form complex with 1:1 molar ratio,and the order of binding ability of three hosts with PPA is HE-β-CD＞HP-β-CD＞Me-β-CD,and also HP-β-CD is more suitable to complex with PPA in molecular state than ionic state.
