用酶解、KCl分级、~(13)C和~(13)H核磁共振谱分析了从棉籽菜中提取的卡拉胶，酶抗性组分和氯化钾可溶组分的~(13)C和~1H核磁共振谱表明，该卡拉胶是由几种多糖组成的。主要成分是卡拉胶，次要成分是部分甲基化的不规则半乳糖，含有很大比例的卡拉胶。
Carrageenan extracted fromEucheuma cottoniiwas analyzed by enzymic hydrolysis, KCl fractionation,13C and1H NMR spectroscopy.13C and1H NMR of the enzymic resistant fraction and of the KCl-soluble fraction prove that the carrageenan extracted fromEucheuma cottoniiis composed of several polysaccharides. The major component is kappa-carrageenan and the minor ones are irregular galactans partially methylated, containing a large proportion of the iota-carrageenan form.
