Studies in the polysaccharide gums with special reference to sapote gum Kilgour, Gordon Leslie
Abstract
Two samples of gum supposedly obtained from Sapotaceae achras and named "sapote gum" were studied using the methods of partition chromatography. The two samples were proven to be entirely different in composition and to constitute in fact two separate and distinct gums. The previously unreported gum was characterized and shown to contain D-xylose, L-arabinose, D-galactose, and one or more glucuronic acids, including some methoxy-glucuronic acid. A new spray reagent was developed for paper chromatography of the sugars, and a novel technique used for making permanent photographic prints of the papergrams. Crystalline sugars were obtained from hydrolysates in pure form by separation on partition columns of powdered cellulose.
