Abstract:

The carrageenans from the cystocarpic stage from the red seaweed Iridaea undulosa were fractionated by means of potassium chloride precipitation. The soluble and insoluble fractions were treated with alkali. The products were refractionated with potassium chloride, giving rise to several fractions, being the main ones those precipitating at low concentrations of potassium chloride. Monosaccharide analyses, metliylation data, spectroscopy and fractionation by anion-excliange chromatography show that, although κ/ι-carrageenans are the main components of the cystocarpic products, other polysaccharides like agarans, mannans, xylans, an α-(1 → 6)-glucan, and other glucans are minor-to-trace constituents of the matrices of this seaweed.
