Tea materials (used tea leaf-A, used tea leaf-B and leaf) were carbonized at 400 ?C for 1 h under nitrogen atmosphere. The material balance of carbonization products (charcoal, vinegar liquid and tar) prepared from each tea material was determined, respectively. The vinegars from tea materials were all alkaline solutions (pH=8.1~9.1). The constituents of vinegar and tar were determined by gas chromatograph-mass spectrometer (GC-MS). The vinegars from tea materials (used tea leaf-A and tea leaf) contained 57 compounds such as alcohols, carboxylic acids, furans, phenols, and nitrogen-contained compounds. The tars from tea materials (used tea leaf-A and tea leaf) contained 83 compounds such as alcohols, ketones, furans, phenols, alkanes, aromatic hydrocarbons, and nitrogen-contained compounds.
