1H and 13C NMR spectral studies of lipiarmycin in CDCl3, and in pyridine-d5 provided evidence for the six partial structures I-VI and the two sugar units 1 and 2. Acid methanolysis led to the isolation of methyl 2-O-methyl-4-O-homodichloroorsellinate-β-rhamnoside, whose structure was determined by spectroscopic methods.
