The Tannic Acid Equivalent (TAE) of the aqueous extracts of the leaves of Dialium guineense and Phyllatus amarus was determined by haemanalysis. The cytotoxic activity of these extracts was also determined using the brine shrimp lethality (BSL) bioassay. TAE of D. guineense was 7.6, while P. amarus was 4.2. LC50 for D. guineense was 260ppm and 370ppm for P. amarus. It was proposed that cytotoxicity may have a direct relationship with TAE.
