2、bstract: In this paper the content, distribution, uptake and transport of aluminum in tea tree were reviewed. Then the main chemical compositions of tea quality which were affected by aluminum, containing tea polyphenols, catechins, caffeine, amino acids, vitamin C, flavonoids, total soluble sugar,

3、aroma components, chlorophyll and so on were reviewed. Moreover some suggestions about tolerance to aluminum in tea tree, aluminum in tea tree followed, microscopic reproduction of main chemical content, aluminum accumulated in different kinds of tea, proper assessment on human safety of aluminum in

4、 tea were proposed.
