Abstract:		"In the present study, are extracted volatile concentrate from Ipomoea asarifolia Poir. and Ipomoea setifera (Desr.) Roem. & Schult. in five-month seasonal gradient. The flowers were subjected to simultaneous distillation - extraction (SDE). The chemical composition of the volatile concentrate was determined by gas chromatography (CG/MS) and (CG-FID). Principal Component Analysis (PCA) and Hierarchical Clustering Analysis (HCA) were performed with the chemical constituents. It was observed that the chemical composition of I. asarifolia varied more with seasonality in relation to the species I. setifera. Furthermore, there is a possibility that germacrene D and alpha-copaene, the main components of the variation volatile of I. asarifolia and with higher concentrations in the rainy months, have ecological importance, attracting specific pollinators for the rainy season. This is the first study to report the chemical composition of the volatile compounds of I. asarifolia and I. setifera along a seasonal gradient"
