title: Identification of a dihydrophaseic Acid aldopyranoside from soybean tissue.
abstract: A previously unidentified abscisic acid metabolite has been isolated and characterized. (+/-)-[2-(14)C]Abscisic acid was incubated in intact soybean leaves and pods; the radiolabeled metabolite was purified by high performance liquid chromatography with on-line scintillation spectrometry detection. Gas chromatography-mass spectrometry was used to obtain spectra of the acetylated and methyl esterified derivatives. The data were consistent with a proposed dihydrophaseic acid-aldopyranoside identity. Conjugation through the 4'-hydroxyl of dihydrophaseic acid is suggested.
