英文摘要: A method for automatic analysis of volatile compounds in essences by headspace-solid phase micro-extraotion-gas chromatography-mass spectrometric (SPME-GC-MS) method was established. By adding some saturated NaCl solution in the essence samples, the interference of extraction solvent can be effectively reduced and the sensitivity of analysis can increase greatly. In identification of volatile compounds in essences, a method was applied by combining the mass spectrum and retention index library search. In the essences the main compounds( detected by HS-SPME) were anetbole (42.4%), butanoic acid 1, 1-dimethyl-2-phenylethyl ester(23.0%), eugenol(5.5%)and beta-caryophyllene (4.3% The precision of this method was between 4.0 and 8.9. The result shows that this method is suitable for the research and the quality control of essences.
