Abstract
Three species of Rhodophyceae namely Chondrus ocellatus, Grateloupia filicina and Gigartina tenella were collected from the coast of Haeundae, Busan, on June 33, 1975. And analysed with respect to the content of carrageenan and such chemical characteristics as the content of sulphate and 3, 6-anhydrogalactose, the solubility in potassium chloride solution. In addition, the same chemical properties were tested on the fractions separated by the different concentration of potassium chloride. Carrageenan content in Chondrus ocellatus was relatively higher than two other samples. All the samples showed more than thirty five percent. The Gigartina-carrageenan showed the highest 3,6-anhydrogalactose content among three samples of carrageenan obtained from different species, and the lowest marked from the Grateloupia-carrageenan. In comparison of the solubility of carrageenan in potassium chloride solution, the precipitation yields at 0.125M potassium chloride were marked in order of Chondrus-carrageenan, Grateloupia-carrageenan, and Gigartina-carrageenan, and the yields at 0.125 M to 2.0 M potassium chloride were in Gigartina-carrageenan, Grateloupia-carrageenan, and Chondrus-carrageenan, and the yields from the soluble fraction at 2.0 M potassium chloride were in order of Grateloupia-carrageenan, Gigartina-carrageenan, and Chondrus-carrageenan. It is noteworthy from the result of characteristics of carrageenans that, 3,6-andydrogalactose content was closely related to the solubility of carrageenans in potassium chloride solution and to the sulphate content which might affect reversibly.
