Albizia harveyi showed a significant cytotoxic activity on the RT-4 cell line (percentage survival 23%) at 10pgIml. It showed a weak cytotoxic activitv on the HT-29 cell line. Dalbergia nitidula. showed a weak cytotoxic activity with percentage death of the RT-4 and HT-29 cell lines of 39 and 34%, respectively, at the 10 pghnl level. These results show that 19 (95%) of the plant extracts tested are non-toxic. One plant (5%), Albizia harveyi showed cytotoxic activity on one of the cell lines used, which was in agreement with the accepted detection level of biological activity by chance. Bioassay guided fractionation of the plant extracts to identify active compound (s) is suggested.enCytotoxicityHuman cancer cell linesPlant extractsArticle
