| 摘 要： | 采用HPLC分析技术对国内茶树种质资源的EGCG3″Me含量及其变化规律进行了研究。结果表明：在200份高多酚茶树种质中发现EGCG3″Me的含量大于1％的茶树种质有6个;茶梢中EGCG3″Me的含量随着叶片成熟度的提高而增加,并且秋季新梢高于夏季新梢;绿茶加工过程能有效保持鲜叶中EGCG3″Me含量,而乌龙茶加工过程的萎凋工序中茶叶中EGCG3″Me含量有明显增加。

| Abstract: | The changes of EGCG3"Me content in different tea germplasms, crop seasons and tea processing were studied by HPLC. The content of EGCG3"Me in six tested tea cultivars was more than 1% among 200 tea germplasms containing high tea polyphenols. The content of EGCG3"Me in new tea shoot was increased with the leaf maturity, and was higher in autumn tea than in summer tea. The content of EGCG3"Me was not changed obviously during the process of green tea manufacture, but increased distinctly during the withering process of the Oolong tea. |
