The new natural products 3,5-bis(2,4-dichlorophenoxy)-2,6-dichlorophenol (ambigol C, 1), a highly chlorinated aromatic compound, and 2,4-dichlorobenzoic acid (2) were isolated from the terrestrial cyanobacterium Fischerella ambigua together with the known compounds ambigol A (3) and tjipanazole D (4). All structures were secured by extensive spectroscopic analysis (1D and 2D NMR, MS, UV, IR). Ambigol C has moderate activity against Trypanosoma rhodesiense.
