Objective To analyze the chemical components of clove oil before and after ?-cyclodextrin inclusion.Methods GC-MS conditions were as follows: DB-1 Capillary gas chromatographic column,programmed temperature rising from 60 ℃ to 230 ℃ at the rate of 10 ℃ /min;split ratio being 1 ∶ 50,Injector port temperature at 230 ℃,and Flame Ionization Detector(FID) temperature at 230 ℃.The components were detected by MS detector.Results GC-MS analysis showed that the main components of clove oil did not changed before and after inclusion,but the proportion of the components had been changed.Conclusion ?-cyclodextrin inclusion have effects on the proportion of clove oil components.
