title: Studies on antibiotics BN-227 and BN-227-F, new antibiotics. II. Chemical structure of antibiotics BN-227 and BN-227-F.
abstract: The structure of a new antibiotic BN-227 was determined as I by physico-chemical methods. The X-ray analysis also suggested the structure of I. The structure of antibiotic BN-227-F was determined as II. The antibiotic BN-227-F was prepared by addition of a solution of ferric chloride to antibiotic BN-227.
