Abstract: The aroma components in black tea were extracted and analyzed by headspace solid phase micro extraction (HS-SPME) coupled with capillary gas chromatography-mass spectrometry (GC-MS). Two different polarity chromatographic columns were used for the separation of the aroma components in black tea. The result of semi-standard non-polar chromatographic column HP-5MS and standard polar chromatographic column CP-Wax were compared by analysis. The results indicated that the separation effect of two different polarity chromatographic column are satisfactory, and there are some differences between the analysis results. Therefore, in the analysis of different aroma components in black tea, we should select suitable chromatographic columns according to the various analytes.
