Preparation and analysis of some acetosugar esters of abscisic acid and derivatives

Racemic abscisic acid (ABA), the cis and trans 1′, 4′-diols (ABA diols) derived from ABA by reduction of the 4′ ketone, and the corresponding 4′-O-acetates were converted into various acetosugar esters by reaction of their cesium salts with the 1-chloroacetosugars derived from glucose, galactose, lactose, and maltose. Analytical separations of the acetosugar esters using high-performance liquid chromatography (LC) on reverse-phase columns were developed. Continuous flow secondary ion mass spectra (CFSIMS) of the various acetosugar esters were obtained and an LC/CFSIMS protocol employing multiple reaction monitoring was used to detect ABA acetoglucose ester in an acetylated extract obtained from plant cells that had been treated with ABA.

Structural Characterization of Abscisic Acid and Related Metabolites by Chemical Ionization Mass Spectrometry

Conjugated metabolites of abscisic acid (ABA) have been characterized by their chemical ionization (CI) mass spectra using isobutane and ammonia as reagent gases.The CI mass spectra usually consist of quasimolecular ions ((+)), and constituent aglycon
