Odontadenia lutea (Apocynaceae) LEAVES: PHYTOCHEMICAL STUDY AND INSECTICIDAL ACTIVITY AGAINST LEAF-CUTTING ANTS Atta sexdens rubropilosa Forel

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 an...
