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.
