摘要
用红外光谱法对羟丙基-β-环糊精的结构进行了定性分析,用气相色谱-质谱联用方法,通过对质谱图解析,详细研究了羟丙基-β-环糊精中羟丙基的分布。此羟丙基-β-环糊精以C2位取代为主,计算得到其平均取代度为6.41。
In this manuscript, the configuration of hydroxypropyl-β-cyclodextrin was studied by qualitative analysis of infrared spectrum,and the distribution of substitutions in hydroxypropyl-β- cyclodextrin was determined by elucidation of mass spectrum gained from GC-MS. The substitutions of the hydroxypropyl-β-cyclodextrin were mainly on C2, and the average degree of substitution was 6.41.
