✦ Synopsis

Acid stability of the monosaccharides used as standards (glucose, mannose and galactose) and also recovery of th.e sugar components released by hydrolysis with methanolic hydrochloric acid of Copra meal mannan (coconut), Yuri glucomannan (lily bulb) and an immunologically active polysaccharide-peptide complex isolated by us from Trz'chofiJz_vtovz mentagroplzytes were examined by gas chromatography. The results obtained indicate that degradation of free sugars occurs to various extents using I, 2.5 and 15 o/o concentrations of hydrochloric acid in anhydrous methanol.
