title: Further studies of the glucomannan from Aloe vahombe (liliaceae). II. Partial hydrolyses and NMR 13C studies.
abstract: The polysaccharide from Aloe vahombe (lilaceae) was submitted to partial hydrolyses by sulfuric, oxalic and phosphoric acid. Some oligosaccharides were isolated and investigated by chemical and 13C NMR spectroscopic methods. Their structure was determined. The results prove unambiguously that in the analyzed material the D-mannose is linked to the D-glucose by beta-1----4 linkages to form a carbohydrate heteropolymer.
