摘要：

A proteoglycan was isolated from the red alga Laurencia spectabilis Postels & Ruprecht (Ceramiales) by extraction in a dilute buffer-NaCl solution followed by gel and anion exchange chromatography. The molecule was composed of 92% carbohydrate and 8% protein. Galactose and uronic acids were the major monosaccharides. Ester sulfate was not detected. A small quantity of hydroxyproline was present in the protein component. The proteoglycan accounted for a very small portion (less than 1% by fr. wt) of the alga. © 1979.
