This paper deals with a possible interpretation value of biochemical methods in comparison with the classic tools of geoarchaeology for the evaluation of formation processes. Organic rich layers from the archaeological site Brandys nad Labem-Vrabi were tested with the aim to determine the origin of several different types of soil organic material by analyzing the content of different sugars. The studied soil body showed signs of cultural layer, redeposited soils, and in situ developed soil. The analysis of different sugars was highlighted: soil samples taken from these layers were analyzed to assess the ratios of mannose + galactose to arabinose + xylose, and of rhamnose + fucose to arabinose + xylose, content of C_org and different nitrates, as well as different rates of absorbance. The results show that the interpretation values of polysaccharides evaluation didn't bring significant results itself, but in combination with classical tools of geoarchaeology may bring interpretable and new results.
