    Abstract:
    Three components differing by their properties from the carminomycins described earlier were isolated from the carminomycin complex. Comparison of the IR and UV spectra, as well as chromatographic and physicochemical properties of 2 of them showed that they were dihydrocarminomycin and its aglycone or dihydrocarminomycinone, which was prepared earlier by synthesis. The third component was a chromophore belonging to 1,4,6-trihydroxyanthraquinone. Investigation of its IR spectrum, physicochemica properties and PMR spectrum showed it to be carboxymethylethylcarminomycinone identical to epsilon-rodomycinone. The data were confirmed by 13C-NMR spectrometry.
