濾紙クロマト法による紅藻粘質物の研究

抄録

Not so many studies have been published which identified the sugar components of seaweeds, since their isolation and identification are rather complicated.
Some of the seaweeds found in Aoshima at Miyazaki city were analysed as shown in Table 1, and their sugar components were also investigated by paper chromatograpy of the acid hydrolysates of hot water extracts (Fig. 1).
The results are as follows:
(1) Principal component sugars in all red algae studied were galactose, xylose and anhydrosugar.
(2) Fucose was detected in four species, but not in other species of red algae. It will be noted here that the presence of this sugar in agar-agar and the mucilage of Gloiapeltis furcata and the absence in Eucheuma mucilage were reported in the previous paper ⁽³⁾.
(3) The mucilage of a green alga, Ulva pertusa gave a remarkably different paper chromatogram from those of red algae, and glucose, xylose and an unknown sugar were detected.
(4) The component sugars of a brown alga, Sargassum Thunbergii markedly differed from those of red algae in the absence of xylose.
