Abstract
—The isolation of uronic acid‐containing glycosaminoglycans from peripheral nerve and spinal cord of monkey was done by combining the cetyl pyridinium procedure and DEAE‐Sephadex column chromatography. The constituent analyses of the isolated GAG‐fractions indicated that hyaluronic acid, chondroitin‐4‐sulphate, chondroitin‐6‐sulphate, heparan sulphate and a testicular hyaluronidase‐resistant galactosamine‐containing GAG were present in both tissues. Hyaluronic acid was the predominant GAG (63 per cent) in both tissues and its level was much higher than in brain. Chondroitin‐4‐sulphate constituted 16 per cent in both tissues. The levels of heparan sulphate and hyaluronidase‐resistant galactosamine‐containing GAG in these tissues were much lower than in brain. The results indicate that the patterns of GAGs in peripheral nerve and spinal cord of monkey are similar but differ from that of brain.
