Carrageenans extracted from gametophytic and sporophytic Chondrus crispus were analysed by hydrolysis, KCl fractionation and 1H NMR spectroscopy. The carrageenan from gametophytic plants is composed predominantly of two KCl insoluble fractions which contain kappa-carrageenan as the major component with 1-carrageenan and sulphated galactans as minor components. The precursor mu- and v-carrageenans were not found in the soluble fraction. The extract from sporophytic plants is composed mainly of a KCl soluble fraction which could be separated into 10 fractions by ion-exchange chromatography. The major component did not show a lambda-type structure but one of a xi-carrageenan.
对从皱波角叉菜配子体和孢子体中提取的角叉菜胶进行了水解、氯化钾分级分离和1H核磁共振光谱分析。配子体植物的角叉菜胶主要由两个不溶于氯化钾的部分组成，其中主要成分是κ-角叉菜胶，次要成分是ι-角叉菜胶和硫酸化半乳聚糖。在可溶部分未发现前体μ-和ν-角叉菜胶。孢子体植物的提取物主要由一个可溶于氯化钾的部分组成，该部分可通过离子交换色谱法分离成10个部分。主要成分不显示λ型结构，而是ξ-角叉菜胶的结构。
