Abstract
The essential oils of Tagetes filifolia have potential for controlling insects that are biotransmitters of virus in plants. The objective of the present study was to evaluate the composition of the essential oil of 78 accessions of T. filifolia of the south-central region of México, established in Chapingo, México. When the plants presented flowering, the extraction of the essential oils was made by simple distrillation process using 500 g of tissue of the complete plant. The chemical composition of the oil was determined with gas chromatography coupled to masses. The principal components of the oil were 4-alilanisole and trans-anethole (4-propenilanisole), individually or in mixture: 1.3% of the accessions only with anethole, 7.7% of the accessions only with alilanisole and 91% of accessions with mixture. In the accessions with mixture of anethole and alilanisole, the proportion of these chemical compounds was variable.
