Mucus-polysaccharide acid hydrolyzate of 7 kinds of fishes was divided into neutral, basic and acidic fractions by using ion-exchange resins. The component sugars in each fraction were analyzed qualitatively and the results showed that all mucus-polysaccharides contain the same components except glucose, the presence of which was not confirmed in some species (Table 1). Due to the fairly close Rf values of galactose and glucose in this study, it was difficult to detect glucose. There remains, therefore a possibility that glucose is also present in all the fishes tested. So, the present results suggest that the mucus-polysaccharides mostly consist of the same component sugars irrespective of the differences in their living circumstances (fresh water or sea water) and in classification system (teleost or cartilaginous fish).
