When the ethereal extract was chromatographed on paper (petroleum ether saturated with 97% methanol), six anthraquinone compounds were detected with R] (I) 0.74, (II) 0.49, (III) 0.85, (IV) 0.12, (V) 0.06 and (VI) 0.04. By separating the ethereal extract on a column of Kapron (with the eluants petroleum-ether; petroleum ether saturated with ethanol; ether; ethanol; and acetone) we obtained the individual crystalline substances I-IV and VI. These substances and also their conversion products, were identified by means of their physicochemical properties, color reactions, UV and IR spectra, and mixed melting points with known anthraquinones.
