Abstract: Solid-phase microextraction (SPME) time and temperature were investigated for the analysis of aroma components in Xinyang Maojian tea by GC-MS. The optimal SPME extraction time and temperature were 50 min and 70 ℃, respectively. A total of 99 aroma components were identified including 32 alcohols (47.83%), 20 hydrocarbons (10.97%), 15 ketones (20.43%), 11 esters (7.24%), 8 phenols (3.4%), 7 aldehydes (7.73%), 3 mixed oxide compounds (1.01%), and 3 nitrogen-containing compounds (1.39%). The characteristic aroma components of Xinyang maojian were linalool, nerol, 6-methyl-5-heptene-2-ketone, amyl alcohol, β-ionone, toluene, 5,6-epoxy-β-ionone, phenethyl alcohol, Z-jasmone, heptaldehyde, 2,2,6 - trimethyl cyclohexanone, benzyl alcohol, 2-ethylhexyl alcohol, nerolidol, and so on.
