Biochemical Studies on “Bakanae” Fungus. Part 49 Chemical Structure of Gibberellins. Part XIV

Abstract

The outline of this report has already been published in this Journal appearing as “Communication to the Editors”. The molecular formula of gibberellin A₂ has been corrected to C₁₉H₂₆0₆. To elucidate the relation between the four gibberellins, we studied their functional groups, skeleton and double bond. As for the results, it was certified that gibberellin A₁, A₂, A₃ (gibberellic acid) and A₄ have functional groups and skeleton as shown in Table I.
