Mycoside B, a specific glycolipid found in bovine strains of Mycobacterium tuberculosis is shown to be a mixture of homologous compounds differing by the nature of the fatty acids. The principal constituent of this mixture is a mycoside B having the molecular formula C84H156O10; it contains one molecule of bound in β linkage to the phenolic hydroxyl of a phenolic, methoxylated glycol C32H58O4, the two aliphatic hydroxyls of which are esterified with 1 molecule of palmitic acid and with 1 molecule of C29-mycocerosic acid. A provisional formula for mycoside B is presented (see formula (V))
