We investigated the reaction rate of DPPH radical scavenging reaction using four kinds of tea catechins ((-)-epigallocatechin gallate, (-)-epigallocatechin, (-)-epicatechin gallate, (-)-epicatechin). As a result, we revealed that the order of reaction rate of DPPH radical scavenging reaction of four kinds of tea catechins is (-)-epigallocatechin gallate > (-)-epigallocatechin > (-)-epicatechin gallate > (-)-epicatechin. And also, the strength of DPPH radical scavenging ability of four kinds of tea catechins under the coexistence of two kinds of antioxidants was evaluated the order of (-)-epigallocatechin gallate > (-)-epigallocatechin > (-)-epicatechin gallate > (-)-epicatechin. Finally, we revealed that the effect on galloyl group and pyrogallol skelton of B ring of tea catechins was the relationship of the reaction rate on DPPH radical scavenging reaction and DPPH radical scavenging ability of four kinds of tea catechins under the coexistence of two kinds of antioxidants.
