  • Components in the acetone extracts of three varieties of tea were analyzed by using gas chromatography/mass spectrometry(GC/MSD).10,13 and 12 compounds were identified from Anxi Tieguanyin,Fujian Jasmine and Wuyi Rock,respectively.The compounds found commonly in the tea extracts were 1,2,3-benzenetriol,1H-purine-2,6-dione,3,7-dihydro-1,3,7-trimethyl-,phenylethyl alcohol,1,2-benzenediol,3-methoxy-,indole and nerolidol(cis-nerolidol in Wuyi Rock).They differed in quantity,type and content in the extracts.The unique substances in the Anxi Tieguanyin extract included butane,1,1-diethoxy-,pyrazine,methoxy-alpha-and beta-methyl-2-deoxy-D-ribopyranoside,oxalic acid and 2-ethylhexyl pentyl ester.The different constituents in the Fujian Jasmine extract were 2-pentene,4,4-dimethyl-,(E),hexanoic acid,2-propenyl ester,1,6-anhydro-beta-D-glucopyranose,3,5-dimethoxy-4-hydroxybenzyl alcohol,pyrazole-5-carboxylic acid and 3-methyl-.The unique compounds in the Wuyi Rock extract were 2-pentene,2,3-dimethyl-,benzene,1,3-dimethyl-,1,6,10-dodecatrien-3-ol,3,7,11-trimethyl-,[S-(Z)]-,1,5-dimethyl-6-oxa-bicyclo[3.1.0]hexane,11,14,17-eicosatrienoic acid and methyl ester.
