| Abstract: | The Hydroxyl radical scavenging activity of green tea water extract and green tea polyphenols extracted was evaluated in vitro. The results obstained shwoed the solution of green tea polyphenols isolated (the concentraation of green tea polyphenols =27.391 mg/ml) had the higher ability to scavenge hydro-radicai than green tea water extract (the concentration of green tea polyphenols =27.391 mg/ml). |
