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. 1 C.D.R.I. Communication No. 2752Keywords
