Abstract
The antioxidative activity was studied for 25 kinds of tea and catechi ns by a new evaluation method using an oxygen electrode. The concentra tion of catechins in 6 types of green tea was analyzed by HPLC. The re sult indicates that the antioxidative activity of green tea depends to some extent on the amount of catechins present.
