Resumo: The leaf parts of Clerodendron trichotomum were extracted and the major essential oils composition and immunotoxicity effects were studied. The analyses were conducted by gas chromatography-mass spectroscopy (GC-MS) revealed that the essential oils of C. trichotomum (CTEO). The CTEO yield was 0.071%, and GC/MS analysis revealed that its major constituents were Hexanal (3.31%), 5-Me-3-heptanone (1.71%), 2,6,6-trime-cyclohexanone (2.23%), 2,6,10,15-tetrame-heptadecane (24.21%) and Linalool (31.2%). The essential oil had a significant toxic effect against early fourth-stage larvae of Aedes aegypti L with an LC sub(50) value of 32.78 ppm and an LC sub(90) value of 93.72 ppm. 2,6,10,15-tetrame-heptadecane was the most toxic among the two major components (2,6,10,15-tetrame-heptadecane and Linalool), with an LC sub(50) value near 43.9 ppm. The results could be useful in search for newer, safer, and more effective natural immunotoxicity agents against A. aegypti.
