A survey of crude plant extracts using a new yeast strain designed to identify DNA-damaging agents resulted in the identification of an extract prepared from Crypteronia paniculata. Bioassay-guided fractionation resulted in the isolation of three active compounds. Two of these were ellagic acid derivatives, namely, 3,3′-di-O-methylellagic acid 4′-O-β-D-xylopyranoside (1) and 3′-O-methyl-3,4-methylenedioxyellagic acid 4′-O-β-D-glucopyranoside (2). The third was identified as kaempferol-3-O-α-L-rhamnoside (3). The three principles exhibited strong, selective cytotoxity toward the RAD52 repair-deficient yeast strain.
