【Abstract】 AIM:To characterize the inclusion complex of volatile oil of Rhodiola crenulata/β-cyclodextrin. METHODS: Some analytical methods,such as DTA,IR,GC,TLC were apllied to the investigation before and after the inclusion. RESULTS: The difference between the inclusion and physical mixture in differential thermal(analysis,) infrared spectra,gas chromatogram and thin layer chromatogram. CONCLUSION: The inclusion of Rhodiola crenulata volatile oil has the characteristic of intramolecular inclusion.更多还原
