      The present work describes the chemical constituents of Odontadenia lutea (Vell.) Markgr. leaves and the toxicities of its extract and fractions against Atta sexdens rubropilosa Forel (Hymenoptera: Formicidae). Chromatographic procedures of the ethanolic extract resulted in the identification of the triterpene β-amyrin, the flavonoid rutin, two fatty acids palmitic and linolenic, and one glyceroglycolipid 3-O-(9,12,15-octadecatrienoyl)-glyceryl-β-D-galactopyranoside, which are known compounds, but they are described for the first time in the Odontadenia genus. The known triterpenes lupeol and α-amyrin were also identified. Structural identification of the compounds was performed by analysis of IR, ESI-MS, and 1D and 2D NMR spectra. The toxicity of its extract and fractions from O. lutea leaves was tested against leaf-cutting ants Atta sexdens rubropilosa Forel by employing ingestion bioassay procedures. The hexane fraction (2 mg mL-1) decreases the average survival of ants from sixteen to six days, causing 98% mortality on the 14th day and 100% at the end of the experiment.
