Abstract

Methyl esters of abscisic acid (ABA) analogues and metabolites dissolved in 0.1-1.0 M sodium methoxide in MeO2H replaced four of their sidechain 1H atoms with 2H (C-4 and C-6) over a period of 4 to 8 weeks. The esters were hydrolysed by adding 2H2O to provide 4H4 labelled free acids. ABA, 1′,2′-epoxy-β-ionylidene acetic and phaseic acids have been labelled in this way. The method can be used to make 3H labelled materials.
