N2 - Water-soluble organic matter extracted from a mull litter horizon under ash and alder was fractionated on Fractogel TSK. With a single fractionation step six fractions could be obtained. The fractions were studied by IR and solution-state 13C NMR spectroscopy as well as by methanolysis. According to 13C NMR spectroscopy, carbohydrates are the dominant constituents of the bulk sample. Alkyl-carbon components are of minor importante and there is only little evidence of aromatic compounds. Data from gas chromatography of methanolysis products shows that sugar acids, sugar alcohols, and cyclitols considerably contribute to the carbohydrate proportion of some of the fractions.
