Abstract
The chemical structure of oligomannoinositides isolated from Wax D of BCG was proposed and discussed. Barium salts of glycerophosphorylinositoldi-, tetra- and penta-mannosides were isolated in pure states from oligoman-noinositides. Fatty acids of oligomannoinositides were proved to be composed of palmitic acid and an acid having the neutral value of 188.
