Eight saccharides were derivatized using 1-(2-naphthyl)-3-methyl-5-pyrazolone (NMP) as pre-column derivatizing reagent, and separated on a reversed-phase Hypersil ODS 2 column (4.6 mm x 200 mm, 5 microm), by high performance liquid chromatography (HPLC) in conjunction with a gradient elution, detected by a diode array detector (DAD), and identified by electrospray ionization-mass spectrometry (ESI-MS) in positive ion mode. NMP reacted with reductive saccharides easily in the presence of 17% ammonia water at 70 degrees C. All linear correlation coefficients for saccharide derivatives were over 0.998 5. The detection limits (at signal-to-noise of 3:1) were 0.58 - 1.1 pmol for saccharide derivatives. The characteristic fragment ions, especially m/z 473, from the cleavage of NMP-labeled saccharides exhibited high regularity for the identification of the composition of saccharide mixture. The established method is sensitive and repeatable for the determination of saccharides.
