Keywords:
Trigonella foenum graecum, Elettaria cardamomum, Tribolium castaneum, Plant oils, GC-MSAbstract
Oils were extracted from seeds of Trigonella foenum graecum as well as from seeds of Elettaria cardamomum, then separated and characterized by Gas Chromatography with Mass spectra GC/MC twelve different compounds of Trigonella foenum graecum oil were identified, the highest rate was for the compound 9, 12-Octadecadienoic acid (Z,Z) which was found with rate of 38.97
،%then accompanied with 31.85% of 9-Octadecenoic acid (Z)-, methyl ester.
On other hand fifty four (54) different compounds were separated from fixed oils of Elettaria cardamomum , the highest rate for the compound 3-Cyclohexene-1-methanol, .alpha.,.alpha.,4-trimethyl-, acetate which was 22.88% then the compound Butyl 9,12-octadecadienoate with a rate of 21.22 % .
The lethal effect of oils against Tribolium castaneum was studied for several periods, the results clarify that the oils of Trigonella foenum graecum and Elettaria cardamomum , significant effects on insect mortality reached to (96.9 and 92.5 )% when they were used with concentration 700 ppm after72 hours of treatment.
