摘要：
Alkaline treatment of a kappa/1-carrageenan from cystocarpic Gigartina skottsbergii and further fractionation with potassium chloride, led to the isolation of a minor product soluble in 2 M KCl with unusual structural features. It contains small amounts of L-galactose and is built up from kappa/1- and lambda-blocks. (C) 1997 Elsevier Science Ltd. All rights reserved.
