A sensitive method for the identification of polysaccharides in pharmaceuticals is described. Polysaccharides are isolated by gel filtration and subsequently hydrolysed. The monomeric carbohydrates obtained are transformed into oxime-trimethylsilyl derivatives and analysed by capillary gas chromatog

โฆ Synopsis
Pyrolysis/capillary gas chromatography is used for the characterization of the monomer composition of various oligosaccharides and polysaccharides including glucosecontaining disaccharides, glucans, a galactomannan and an arabinogalactan. The chromatograms showed many common pyrolysis products, but also unique anhydrosugar products (e.g., 1,6-anhydroglucopyranose, 1,4-anhydroarabinopyranose, 2,6-anhydrofructofuranose) derived from each type of saccharide unit present in the samples. Reasonable values of the monomer composition of the polysaccharide can also be obtained from the pyrograms. The method is rapid and direct, requiring no sample preparation.

Direct analysis of polar solutes by supercritical fluid chromatography (SFC) has been somewhat limited because the mobile phases in common use are all relatively nonpolar. Derivatization is demonstrated as a viable means for facilitating the SFC separation of sugars. Oligo-and polysaccharides contai
