| Abstract | For better use of tea plant (Camellia sinensis) flower resources, biochemical components and contents of eight tea cultivars flowers were investigated. Volatile aromatic compounds were extracted by simultaneous distillation and solvent extraction (SDE) and determined using Gas Chromatography (GC) and Gas Chromatography/Mass Spectrometry (GC-MS). The contents of tea polyphenols, amino acids, caffeine, soluble sugars and soluble proteins was assayed by colorimetric method with ferrous tartrate, ultraviolet spectrophotometric method, anthrone colorimetric method and coomassie brillient blue method, respectively. Among the eight cultivars flowers there were big difference in contents and numbers of volatile aromatic compounds. The greatest numbers of volatile aromatic compounds in flowers was 50, and the least numbers of volatile aromatic compounds in flowers was 9. The major constituents of volatile aromatic compounds in flowers included alkanes, alcohols, esters, ketones, aldehydes and alkenes. Acetophenone and tricosane were found in each cultivar flowers. However, The content of acetophenone, 2-heptanol, (S)-, 1,6-octadien-3-ol, 3,7-dimethyl-, 1,2-benzenedicarboxylic acid, mono(2-ethylhexyl) ester and di-n-octyl phthalate were higher in some flowers. The result also indicated that tea flowers were rich in soluble sugars and soluble proteins. |
