Puer tea is a traditional beverage originating from Yunnan area of China. We have analyzed 11 different commercial tea brands provided by Daboo Culture and Art Center. This study was carried out to evaluate the contents of polyphenols, antibacterial activity, antioxidantive ability and physiological activities of extracts from Puer tea. The electron donating ability was ranged from 57.26~99.16% and SOD-like activity was ranged from 1.4~10.4%. The inhibitory effect on the growth of cancer cell lines was examined by MTT assay. The Puer tea extract exhibited the greatest inhibitory effect at the concentration of 2% for all cancer cells tested.
