Abstract

The gums and mucilages are hydrophilic colloids of high molecular weight. Some are completely soluble in water, forming viscous solutions of gels, others swell and absorb considerable quantities of solvent without dissolving. They are not soluble in the common organic solvents. Gums are usually characterised as plant exudates, often from infected tissues, whilst mucilages are obtained by the extraction, with water, of various plant organs, for example, seeds (e. g. linseed, Linium usitatitissimum), bark (e. g. slippery elm, Ulmus fulva), mosses (e. g. Irish moss), seaweeds (e. g. agar, Gelidium crinale, Gracilaria confervoides). In our present state of knowledge, it is not possible to decide whether certain of these substances should be classified as gums or mucilages.
