摘要：

Cirramycin A, a macrolide antibiotic, has been found to consist of one major (A1) and several minor components (A2, A3, A4 and A5). The majoractive substance, cirramycin A1 (C31H51NO10), was isolated as a single component and characterized in detail. It has a strong ultraviolet absorption peak at 241 mμ and its chromophore is suggested to be an α, β-unsaturated γ, δ-depoxide carbonyl system. Cirramycin A1 contains the basic sugar mycaminose but lacks a neutral sugar in the molecule. © 1969, JAPAN ANTIBIOTICS RESEARCH ASSOCIATION. All rights reserved.
