Abstract
THE ‘amyloid reaction’ frequently used in the staining and identification of plant materials1 has been modified by Gaillard2 as a test to distinguish between linear and branched polysaccharides. Linear polysaccharides are precipitated from 1 per cent solution in 30 per cent aqueous calcium chloride by the addition of aqueous potassium iodide–iodine solutions, whereas branched polysaccharides are not. An examination of this reaction has been carried out to investigate its possible use in wood chemistry.
