Preparation and Appraising of Eucalyptus Oil?-cyclodextrin Inclusion Compound / 中国药房

ABSTRACT

OBJECTIVE:To prepare and appraise eucalyptus oil?-cyclodextrin inclusion compound,and to testify the feasibility of transforming the dosage form of eucalyptus oil by clathration techniques.METHODS:The physicochemical properties of inclusion compound was identified by thin-layer chromatography(TLC),infrared spectroscopy(IR),ultra-violet spectroscopy(UV)and gas chromatograph mass spectrometer(GC-MS),respectively.Meanwhile,the changes in constituents and clathration outcomes of eucalyptus oil before and after clathration were also investigated.RESULTS:The analytic result of TLC,IR and UV showed that stable inclusion compound has been formed from eucalyptus oil and?-cy?clodextrin.The result of GC-MS demonstrated that there was no significant change in the essential components and the percentage composition of eucalyptus oil before and after inclusion.CONCLUSION:Stable inclusion compound can be made from eucalyptus oil and?-cyclodextrin meanwhile without changes in main components and the percentage composition of eucalyptus oil.
