title: The structures of new antifungal antibiotics, benanomicins A and B.
abstract: Structures of new antifungal antibiotics, benanomicins A and B were determined to be N-[[5-[6-deoxy-3-O-(beta-D-xylopyranosyl)-beta-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-(beta-D-xylopyranosyl)-beta-D- galactopyranosyloxy]-5,6-dihydro-1,6,9,14-tetrahydroxy-11-methoxy- 3-methyl-8,13-dioxobenzo[a]naphthacen-2-yl]carbonyl]-D-al ani ne, respectively, by spectral analyses and chemical degradation studies.
