## Magic-angle 13C n.m.r. spectra have been obtained for a series of vitrinite concentrates. Proper modification of the cross-polarization pulse sequence allows separation of protonated and nonprotonated carbon resonances. This technique is used to determine the relative fraction of nonprotonated
The Na,CO,-soluble pectic polysaccharides of mature onions were separated by anion-exchange chromatography, and the structural features of two of the pectic polysaccharides were examined by methylation analysis and t3C-n.m.r. spectroscopy. The oligosaccharide side-chains containing j3-o-galactose we
