Structures of new antifungal antibiotics, benanomicins A and B were determined to be N-[[5-[6-deoxy-3-O-(β-D-xylopyranosyl)-β-D -galactopyranosyloxy]- 5, 6- dihydro-1, 6, 9, 14-tetrahydroxy-11-methoxy-3-methyl-8, 13-dioxobenzo[a]naphthacen-2-yl]carbonyl]-D-alanine and N-[[5-[4-amino-4, 6-dideoxy-3-O-(β-D-xylopyranosyl)-β-D-galactopyranosyloxy]-5, 6-dihydro1, 6, 9, 14-tetrahydroxy-1 1 -methoxy- 3 -methyl- 8, 13 -dioxobenzo[a]naphthacen-2-yl]carbonyI]-Dalanine, respectively, by spectral analyses and chemical degradation studies.
