| Abstract: | The main chemical composition including amino acids,tea polyphenols, caffeine,chlorophyll of Tongbaiyuye tea made by five varieties:Longjingchangye,Longjing43,Pingyangtezao,Baihaozao and Wuniuzao from tea seed multiplication farm in Hennan province were determined.As the results,the content of tea polyphenols was highest of Longjingchangye, the flavour was more concentrated ; the content of amino acids of Pingyangtezao was more higher than the else; the content of water extracts of Baihaozao was the most and the flavour was more concentrated;andthe chlorophyll of Pingyangtezao was highest. |
