Cumaru oil (Dipteryx odorata) has chemical properties that make it a sought-after input in the cosmetics, perfumery, alternative medicine and food industries. The appreciation of these essential oils, as well as other native plants, not only reinforces Brazil's position as a leader in the production and export of natural products, but also strengthens its identity on the international scene, promoting sustainability and environmental preservation. For the analysis of carbon-13 (δ¹³C), oxygen-18 (δ¹⁸O) and deuterium (δD) of the essential oil extracted from Cumaru seeds, isotope ratio mass spectrometry (IRMS) was used to determine the authenticity and quality of Cumaru oil. The results obtained allowed validating the methodology used both in the analysis and in the extraction of the essential oil, which used solvents such as ethanol and ethyl acetate, and demonstrated its ability to distinguish genuine products from fraud.
