Stability and bioactivity of gibberellic acid in different solvents

Stability and bioactivity of gibberellic acid in different solvents

HPLC chromatograms indicated that transformation of gibberellic acid (GA3) to the corresponding dicarboxylic acid via iso-GA3 occurred in weak alkaline solution. The bioactivity of this dicarboxylic acid was about 20% that of GA3 and above 0.3 M NaOH this compound appeared to decompose. Aqueous solu...

Zusammenfassung:HPLC chromatograms indicated that transformation of gibberellic acid (GA3) to the corresponding dicarboxylic acid via iso-GA3 occurred in weak alkaline solution. The bioactivity of this dicarboxylic acid was about 20% that of GA3 and above 0.3 M NaOH this compound appeared to decompose. Aqueous solutions of NaOH cannot, therefore, be used as solvent in bioassays of GA3 activity.
