N2  - In this study, total phenolic content, antioxidant, antimicrobial activity and colour parameters of black and green teas were investigated regarding to brewing concentrations of teas. Total phenolic content of green teas ranged between 309-3915 mg GAE/L while in black teas they changed from 152 to 2089 mg GAE/L. The highest antioxidant activity was detected in green teas with 1942.761 μmol TE/L. Antimicrobial activity analysis showed that brewing the black teas at ratios of 200 and 100 mg/ml exhibited antimicrobial activity on P. aeruginosa while they did not show inhibitory effect on S. aureus and E. coli. However, all green tea concentrations exhibited antimicrobial effect on P. aeruginosa.
