| Abstract: | Objective:To study the chemical constituents of the essential oils from Calonyction muricatum.Method: The essential oils were extracted by supercritical carbon dioxide extraction,and then the constituents were separated and identified by gas chromatography-mass spectrometer(GC-MS),and then their relative content was determined by the area normalization.Result: Forty-six compounds were isolated and identified that composed about 92.80% of the total essential oils.The principal constituents are linoleic,palmitic acid,stearic acid,precocene Ⅱ.Conclusion: Fatty acid is the main constituent of the essential oil,accounting for 72.32% of the total. |
