Detection and isolation of new glycosides in culture broths of Streptomyces hygroscopicus.

Elbein, A. D. (Purdue University, Lafayette, Ind.) J. A. Holowczak, Henry Koffler, and H. R. Garner. Detection and ìsolation of new glycosides in culture broths of Streptomyces hygroscopicus. J. Bacteriol. 91:604-608. 1966.-Four new compounds not previously reported have been isolated and purified from the culture broths of Streptomyces hygroscopicus. The data presented suggest that these compounds may be structurally related to hygromycin A, having similar aglycons but differing in their sugar moieties. Two of the compounds apparently contain d-glucose or l-fucose as their sugar components. The others, like hygromycin A, form crystalline 2,4-dinitrophenylhydrazones, and may contain unusual keto sugars.
