Thin layer chromatography of lemon grass oil indicated five compounds having Rf values of 0.13, 0.15, 0.29, 0.58 and 0.76. The bioefficacy of lemon grass oil and its fractions were tested against the adults of Tribolium castaneum. Lemon grass oil was found to be effective at all the concentrations tested (50–2000 μg g−1) Polar fraction was found to be more active than the non-polar fraction. The polar fraction was purified and characterized.
