A new polysaccharide was isolated from corn smut galls in their early stages of development. Total acid hydrolysis proved this substance to be a glucan. On partial acid hydrolysis, followed by column chromatography, glucose, gentiobiose and laminaribiose were isolated and identified. Gentiotriose and laminaritriose were also isolated and inferred. Infrared spectra as well as low specific rotation of the polysaccharide indicated that the glycosidic linkages might be of the β type. When oxidized by periodate, the polysaccharide consumed 1.91 moles of oxidant and yielded 0.94 mole of formic acid per mole anhydroglucose, suggesting that about 90% of glucose units may be joined by β-(1→6) linkages, and the remainder by β-(1→3) linkages. The glucan was tentatively termed as “zeagallan.”
