Abstract: The change of aroma constituents in Pu-erh raw tea during the pile-fermentation process were determined by HS-SPME/GC-MS. Results showed that the alcohols and hydrocarbons decreased distinctively, however, the heterocyclic oxygen compounds and esters increased distinctively during the pile-fermentation process. 1,2,3-Trimethoxybenzene was the most abundant component among the heterocyclic oxygen compounds, and its content reached the highest when the pile-fermentation process finished, and some main aromatic components, and relative contents which were obvious differences in Pu-erh raw tea and Pu-erh tea were analyzed.

Key words: Pu-erh tea, aroma constituents, HS-SPME, change, process, pile-fermentation
