Abstract

Caffeine, theophylline, theobromine, (+) catechin, (-) epicatechin, gallic acid and theaflavin obtained from black tea (Camellia sinensis) inhibit passive cutaneous anaphylactic reaction in mice without affecting acetylcholine, histamine and serotonin induced broncho-constriction in the guinea pig. Theophylline and theaflavin antagonise only prostaglandin F₂ alpha induced bronchoconstriction.
