Structure 1 has been established for Papulacandin B (C47H64O17), a new antibiotic from Papularia sphaerosperma (Pers.) Höhnel by means of spectral analysis of 1 and some derivatives and degradation products. Base catalysed hydrolysis of 1 gave the two unsaturated fatty acids 2 and 3 and the spirocyclic diglycoside 4. The structure of 4 was determined by further degradation reactions
