Nonderivatized gibberellin glucosyl conjugates were analysed by capillary reversed-phase high-performance liquid chromatography/mass spectrometry. Positive as well as negative ion mass spectra were obtained by frit fast atom bombardment. The spectra were found to provide useful information for the i

## Abstract 2โ€__O__โ€GA~29~ฮฒโ€Dโ€glucopyranoside (1e) and 13โ€__O__โ€GA~29~, ฮฒโ€Dโ€glucopyrโ€anoside (1h) were synthesized from GA~29~ methyl ester (1b). Their structures were confirmed by ^1^H NMR and GCโ€MS. Likewise, [17โ€^13^C,T~2~]โ€labelled 1e and 1h could be obtained. From [17โ€^13^C,T~2~]GA~20~ (2a) an
