| Abstract: | The essential oil of thyme is extracted by ultra-high pressure method. The effects of pressure, solid- liquid ratio, grinding degree and holding time on the extraction rate of thyme essential oil are investigated. The chemical constituents of thyme essential oil are analyzed by gas chromatography-mass spectrometry. The results show that the optimum conditions for ultra- high pressure extraction of essential oil from thyme are as follows: pressure is 410 MPa, solid-liquid ratio is 1∶28, crushing degree is 50 meshes, holding time is 4 min, extraction temperature is at room temperature, and the average extraction amount of thyme essential oil is 11.236 mg/g. GC-MS analysis confirms that there are 46 components in thyme essential oil, accounting for 97.949% of the total peak area. The main components are thymol (43.925%) and p-cymene (16.112%),etc. |
