摘要
采用冷冻干燥法制备白藜芦醇-羟丙基-β-环糊精包合物。采用正交试验以包合率为指标筛选最佳工艺条件:白藜芦醇∶羟丙基-β-环糊精为1∶2(物质的量的比),包合温度为20℃,包合时间为60 min。以红外光谱、紫外光谱方法对包合物进行鉴定,初步证明包合物已形成。通过测定包合率的大小证明羟丙基-β-环糊精包合白藜芦醇效果较好。
The inclusion complexes were prepared by freeze - drying method. The optimum preparation condition was studied by orthogonal test with encapsulation rate as the index of evaluation： the ratio of Resveratrol to HP -β- CD 1 ： 2, inclusion temperature 20℃, inclusion time 60 minutes. Its structure was identified by IR, UV absorption spectrum, hence preliminarily proving that the inclu- sion complexes of Resveratrol - hydroxypropyl -β- cyclodextrin were satisfactorily formed.
