The repellent properties of different fractions isolated from Lantana camara flowers by using steam distillation, solvent partition and chromatographic methods were evaluated against Aedes mosquitoes. Maximum protection time of one fraction eluted by chloroform from a silica gel column was 3.45 h. One application of this fraction gave 100% protection for 2 h and may protect 75.8% at 7 h (t = 7.00, P < 0.001) against the bites of Aedes mosquitoes. Further purification of the most efficient fraction into pure compounds did not result in any increase in repellency.
