Chemical composition, Antioxidant and Mosquito larvicidal activities of essential oils from Tagetes filifolia, Tagetes minuta and Tagetes elliptica from Perú

Abstract

The chemical compositions of the essential oils from the aerial parts of Tagetes filifolia Lag. („Anís serrano“), Tagetes elliptica Sm. („Chincho“) and Tagetes minuta L. („Huacatay“) from Perú were determined by gas chromatography-mass spectrometry. The main constituents of the essential oils were: trans-anethole (88.2%) and methyl chavicol (10.9%) for T. filifolia; trans-ocimenone (51.7%), cis-tagetone (17.7%) and cis-ocimenone (7.7%) for T. minuta; and 6,7-epoxy myrcene (31.9%), dihydrotagetone (22.0%), trans-ocimenone (12.0%) and cis-tagetone (8.0%) for T. elliptica.
