This paper reports the presence of gibberellic acid (GA3), abscisic acid (ABA), indole-3-acetic acid (IAA) and zeatin in the brain, liver and kidney of laboratory mice. The identification of these plant growth regulators (PGRs) in animal tissues after the dietary treatment by GA3 or ABA on F1 offsprings in two different exposure periods was studied. Thin layer chromatographic (TLC) techniques and spectrophotometric assay methods were used for this study. Results show that assayed PGRs accumulate in animal tissues and accumulation of these substances is being attributed to their feed source and exposure to PGR as an effective factor.
