Objectives: To study the anticancerous property of leaves of Clitoria ternatea L.
Methods: The leaves were soaked in 50percent aqueous ethanol, extract was filtered and concentrated. Cytotoxicity of the extract was tested by brine shrimp lethality assay.
Result: The experimental results revealed that 0.28-0.38percent concentration of 50 percent aqueous ethanolic leaf extract possessed cytotoxic potentiality against brine shrimp.
Conclusion: Hence the plant may be identified as a source of bioactive principle having  antitumour activity.
Key words: cytotoxicity, lethal conc., mortality, LC50, brine shrimp, phytochemical products
