Abstract:
OBJECTIVE:To analysis and identify the liposoluble constituents extracted with supercritical CO 2 fluid ex-traction(SFE)from atractylodes macrocephala by gas chromatography-mass spectrometry(GC/MS).METHODS:Volatile oil was extracted from atractylodes macrocephala,to analsis and identify the chemical components in liposoluble constituents with GC/MS,DB-5MS capillary column was the chromatographic column and helium was carrier gas,the flow rate was 2.0ml/min,and the column temperature was raised from 70℃ to 250℃ at an increasing rate of 10℃/min.EI ion sources were adopted in mass spectra.RESULTS:A total of 19 chromatographic peaks were separated and identified,most of which were unsatu-rated fatty acids and esters,accounting for 96.2% of the total peak area.CONCLUSION:Using GC/MS,the chemical com-position of the liposoluble constituents in atractylodes macrocephala can be analyzed,which provides references for the further exploitation and utilization of atractylodes macrocephala.
