| Abstract: | A mixture of several known saccharides was analyzed by liquid chromatography/mass spectrome-try with a thermospray interface,in their spectra the main characteristic ions include the adduct ions,M + NH4]+,M+(NH3)(H2O)H]-etc. ,and the fragment ions produced through the consecutive water loss of the adduct ions. Based on these results, we further investigated the free monosaccharices in ramie and deduced the constituents from their spectral features. The experimental results agree with those obtained by gas chro-matography combined with derivation. |
