摘要
目的:筛选制备银杏提取物与羟丙基-β-环糊精(HP-β-CD)包合物的最佳工艺,并进行包合物的鉴定。方法:采用正交设计试验,以包合率为指标筛选最佳工艺条件,以溶液-搅拌法制备包合物;以相溶解度法、差示扫描量热(DSC)法、红外分光光度法对包合物进行鉴定。结果:最佳包合条件为银杏提取物:HP-β-CD=1·5:1(质量比),搅拌时间为6h,包合温度为50℃。结论:银杏提取物与HP--CD初步被证明形成包合物。HP--CD对药物有较好的增溶作用。
OBJECTIVE: To optimize the preparation technology of Ginkgo biloba extracts - hydroxyprop -β- cyclodextrin(GBE HP-β- CD) inclusion compounds and to identify this inclusion compound. METHODS: The optimum preparation condition was studied by orthogonal test with encapsulation rate as the index of evaluation. The inclusion compounds were prepared with solution- agitating technique. The inclusion compounds were identified by phase solubility diagram, differential scanning calorimetry(DSC) and infrared spectroscopy methods, respectively. RESULTS: The optimum inclusion condition was as follows: the ratio of GBE to HP -β-CD= 1.5 : 1; agitating time=6 h; inclusion temperature= 50℃. CONCLUSION: It has been preliminarily proved that it is possible for Ginkgo biloba extracts and hydroxyprop -β-cyclodextrin to be made into inclusion compounds. HP-β- CD has satisfactory solublization on Ginkgo biloba extracts.
