Bicyclogermacrene (21%), (Z)-'-ocimene (19%), '-humulene (8%), '-pinene (8%) and spathulenol (6%) were the main constituents of the oil. The identification of the separated volatile organic compounds was accomplished through comparison of mass spectra of peaks with those stored in the in-house “Baser Library of Essential Oil Constituents.” Additional confirmation was achieved by comparison of retention indices from compound peaks. From inspection of chromatograms in the GC-MS analysis, there was an unknown compound at RI 2931 with a mass spectrum similar to suberosin in the Wiley GC-MS Library. Since this compound was not present in the Baser Library, we could only tentatively identify this compound based on similarity of the mass spectrum to the one in the Wiley GC/MS Library. Due to insufficient oil yield, we synthesized suberosin in two steps and confirmed its structure by 1D NMR and GC-MS analyses. As part of our continued research to discover botanical insecticides for use in mosquito control as repellent and larvicides, suberosin was investigated for mosquito biting deterrent and larvicidal activity against Aedes aegypti. Suberosin showed good but lower biting deterrent than DEET (N,N-diethyl-m-toluamide). In larval bioassays, suberosin had good activity against 1-d-old Ae. aegypti larvae. These results indicate that this compound may be useful in developing its use as a mosquito control agent. |
