H. Specifera在结构上与卡拉胶非常相似。然而，目前还没有关于H. charoides。在我们的水溶性多糖，葡甘露聚糖的研究，我们研究了从H.charoides的多糖的化学性质。一百克干燥的粉末状H.用8升热的氯化氢水溶液（pH 5）萃取charoides 2·3hr，过滤，得到6升粘液提取物。的浓缩溶液
polysaccharide from H. specifera is very similar in structure to that of ƒÈ-carrageenan. However, no report exists on the chemical properties of the mucil aeinous polysaccharide from H. charoides. In connection with our study of the water soluble polysaccharide, glucomannan, we investigated the chemical nature of the polysaccharide from H.charoides. One hundred gram of dried, powdered H. charoides was extracted with 8 liters of hot, aqueous hydrogen chloride (pH 5) for 2•`3hr and filtered to give 6 liters of a mucilaginous extract. A concentrated solution of
