Abstract

AB023, a complex of new polyene Antibiotics, was isolated from a soil Streptomyces strain. The two main components, pentaene Antibiotics AB023a and AB023b, were separated and purified by preparative chromatographic methods and their structures were determined by extensive NMR and mass spectrometric studies.
