Carbohydrates in Cold Water Extracts of a Pine Forest Soil.

Abstract

Water-soluble carbohydrates in a pine forest soil profile from Western Norway were studied by partition chromatography. The soil samples were first extracted with ether followed by cold water, and the water extracts were concentrated in vacuo. Water-soluble polysaccharides were precipitated with ethanol, separated from the mother liquid by filtering, and hydrolyzed. Most of the sugars observed were quantitatively determined, and their amounts and distribution in the profile layers discussed.
