Abstract:
Bioassay-guided fractionation of the EtOH extract of the bark of Uncaria guianensis (Aubl.) Gmel (Rubiaceae) using a yeast-based assay for DNA-damaging agents has furnished the two weakly but selectively active indole alkaloids uncarine C (1) and uncarine E (2) as the major bioactive constituents in this assay.
