Research on the hemicelluloses of the wood of maritime pine of Landes . I. Separation, identification, and study of the constitution of aldotrio-uronic, aldobio-uronic, and uronic acids liberated by partial acid hydrolysis of the wood



Research on the hemicelluloses of the wood of maritime pine of Landes . I. Separation, identification, and study of the constitution of aldotrio-uronic, aldobio-uronic, and uronic acids liberated by partial acid hydrolysis of the wood



Bull Soc Chim France (11/12): 2074-2085



The acid fraction obtained by the partial hydrolysis of the wood of maritime pine by dilute sulfuric acid was fractionated by successive chromatog-raphy on anion exchange resin and hydrocellulose (or infusorial earth) into 14 constituents of which 11 were identified as follows 2 aldotrio-uronic acids, 6 aldobio-uronic acids, 2 hexuronic acids, and a mono-O-methyl hexuronic acid. One of the aldotrio-uronic acids and 5 of the aldobio-uronic acids were identified for the first time in a hydrolysate of wood.
