Gibberellenic acid is a gibberellin-type intermediate compound featuring a tetracyclic diterpenoid structure. It is produced from the thermal decomposition of Gibberellic acid (GA3) in aqueous solution. This compound is thermally unstable in water, leading to further conversion into allogibberic acid (approximately 80%) and 9-epiallogibberic acid (approximately 10%). Gibberellenic acid holds significant research value in the study of gibberellin degradation pathways and structural analysis.
