It was found that the chemiluminescence arising from the reaction of luminol with H 2 O 2 involving Co(II)‐catalyzed in alkaline solution could be strongly inhibited by gibberellic acid. Based on this observation, a new flow injection chemiluminescence method is proposed for the determination of gibberellic acid. The detection limits of the method are 0.09 ng mL −1 gibberellic acid. The method was successfully applied to the determination of gibberellic acid in bacteria‐free culture liquid.
