Abstract
It is well known that the major neutral monosaccharide components released from soil by acid hydrolysis are glucose, galactose, mannose, arabinose, xylose, ribose, rhamnose and fucose. A colorimetric determination of the saccharide mixture released from soil is unsatisfactory for determining an accurate figure for soil saccharides. More precise information can be obtained by the determination of monosaccharides after separation by chromatography. Paper and thin-layer chromatography for quantitative analysis are rather time consuming and laborious. The gas chromatographic procedure was applied successfully for the analysis of sugars in soil hydrolysates by OADES et at. (7). Preparation of the various derivatives for gas chromatography still requires many steps, much handling of the sample, and considerable time, although final analysis of the product derivative is accomplished in an hour or two.
