ABSTRACT
OBJECTIVE:To optimize the preparation technology of Ginkgo biloba extracts-hydroxyprop-?-cyclodextrin(GBE-HP-?-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 diagra-m,differential scanning calorimetry(DSC) and infrared spectroscopy methods,respectively.RESULTS:The optimum inclusion condition was as follows:the ratio of GBE to HP-?-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-?-cyclodextrin to be made into inclusion compounds.HP-?-CD has satisfactory solublization on Ginkgo biloba extracts.
