摘要：
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.
