GLC-EI-MS total ion current profiles and selected mass spectra of the trimethylsilyl methyl-ester methyl glycoside derivatives of the monosaccharides generated from RG-II. a, b The GLC-EI-MS total ion current (TIC) profile of the TMS derivatives generated from wine (a) and celery (b) RG-II. The identity of the monosaccharide derivative in each peak is shown. The peak eluting at ~ 39 min is the TMS derivative of myo-inositol used as an internal standard. c The EI mass spectrum of selected monosaccharide derivatives generated from wine RG-II. The multiplication factor (> X) used to expand selected regions of each mass spectrum is shown
