This work aims the use the enfleurage experiment for teaching Chemistry, by using commercially available and accessible materials, such as hydrogenated soybean fat (GSH) and flower petals. The pedagogical approach explored in the experiment can be used in different phases of the flowering method, making it possible to correlate many chemistry contents with everyday activities. Among the contents that can be studied applying the flowering process, we highlight the molecular chemical structures of oil constituents, indicating the functional groups and polarized covalent bonds, the intermolecular interactions existing in the essential oil extraction processes with GSH and in the liquid-liquid extraction using ethanol as an organic solvent. Thus, the flowering method widely used in antiquity and sometimes represented in films in obtaining flower essences can help as an interesting pedagogical tool to develop interest and contribute to the understanding of chemistry contents.
