Effect of the decoction of A. marmelos on bacterial enterotoxins. (A) Production of E. coli heat labile toxin (LT) and its binding to GM1. (B) Production of cholera toxin (CT) and its binding to GM1. C: Control, toxin in medium alone; M1: LT in medium with 5 mM 2-mercaptoethanol; M2: CT in medium with 1 mM 2-mercaptoethanol; G: Toxin in medium with 50 mM gallic acid; D: Toxin in presence of decoction. Values represent mean ± standard error (n = 3) of percentage production/binding relative to respective control (100%); * P < 0.05.
