Cytotoxic activity of Vitex trifolia purpurea extracts.

Defatted 85% crude hot aqueous methanol extract of vitex trifolia purpurea (ame) successively extracted with,chloroform and ethyl acetate. cytotoxicity of (ame),chloroform methanol extract (ce),ethyl acetate methanol extract (ee) and the residue obtained from methanol extract after successive extraction (rme) have been evaluated on brine shrimp (artemia salina) and hep-g2 cell lines as well. in brine shrimp lethality bioassay the results revealed that the (rme) is the most potent one with lc50 value 173 microg/ml while lc50 values of (ame),(ce) and (ee) was 180,199 and 286 microg/ml,respectively. as well as the results of cytotoxic assay against hep-g2 cell lines are in full agreement with previous results,with ic50 values 6,10.7,20.8 and 65.8 microg/ml for (rme),(ame),(ce) and (ee),respectively.
