The effects of tannins and related polyphenols on KO2- and compound 48/80-induced histamine release from rat peritoneal mast cells were examined. Pretreatment with hydrolyzable tannins (1-100 microM) significantly inhibited KO2-induced histamine release. Dimeric ellagitannins, which have hexahydroxydiphenoyl (HHDP) and valoneoyl
