Evaluation of the antioxidative activity of tea by an oxygen electrode method

Biosci Biotechnol Biochem. 1998 Jan;62(1):175-7. doi: 10.1271/bbb.62.175.

Abstract

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