Catechins of green tea were investigated an effect on carrageenan-induced inflammatory edema. The major part of catechins in green tea are epicatechin(EC), epigallocatechin(EGC), epicatechin gallate(ECg) and epigallocatechin gallate(EGCg). It was found previously that ester type of those catechins had significant inhibitory action for thrombin on blood coagulation. In this study, EGCg in catechins of green tea inhibited markedly plasma kallikrein(p-KL), but EGC did slightly. Both EGCg and EGC scarcely inhibited glandular kallikrein(g-KL). EGCg indicated an inhibitory effect on carrageenan-induced inflammatory edema in foot in mice, but not recognized EGC.
