Use of the orcinol - Sulphuric acid reaction in the positive identification of certain monosaccharides from a salivary mucoid

Abstract

AN approximate identification of sugars separated from hydrolysates of biological material can usually be made by paper chromatography. Positive identification is usually achieved by the measurement of some specific physical property such as optical rotation, or the preparation of derivatives possessing characteristic melting points. It frequently happens that sugars separated from hydrolysates are present in insufficient amounts to enable such methods of identification to be used. © 1956 Nature Publishing Group.
