Extracts of Rumex hymenosepalus have shown antitumor activity against the Sarcoma 180 and Walker 256 test systems of the Cancer Chemotherapy National Service Center, Bethesda, Md. The extracts have been fractionated by means of solvent extraction and paper chromatography into two distinct fractions. The partial characterization of these fractions is described, including the characterization of leucocyanidin as one of the constituents and the identification of benzoic acid as a hydrolysis product of a polyphenolic ester.
