| Abstract: | Objective To analyze the volatile components from dried plum extracted by supercritical CO2 fluid extraction（SFE）.Methods The chemical components were analyzed by GC-MS-DS under the conditions of extraction pressure 35 Mpa,extraction temperature 40 ℃ and extraction time 2 h.Results 48 components from dried plum were separated by SFE and identified by GC-MS,and the main constituents were 6-Octadecenoic acid（17.11%）,n-Hexadecanoic acid（12.33%） and 5-（hydroxymethyl）-2-Furancarboxaldehyde（10.68%）.Conclusion The method established here was effective and feasible which was the base of high efficiency extraction,purification and industrialized preparation of the volatile components from dried plum. |
