Breu canauaru is well-known in the Brazilian Amazon for its purported medicinal and magical properties, but its origin has remained an enigma for centuries. Locals commonly believe that breu canauaru is an exudate produced by a frog—the canauaru frog—but most ethnoscientists attribute its production to resiniferous Burseraceae. The aim of the study was to gain insights into the origin of breu canauaru by investigating the chemical composition of one sample, donated by a quilombola from the municipality of Oriximiná (Pará State, Brazil). It was ground and hydrodistilled to obtain the volatile oil. Subsequently, the “resinous” residue from hydrodistillation was extracted with dichloromethane in a Soxhlet apparatus. The volatile oil and the dichloromethane extract were analyzed by gas chromatography coupled with mass spectrometry. The breu canauaru sample consisted of terpenoids (mono-, sesqui-, di-, and triterpenoids) and n-alkanes. The main constituents of the dichloromethane extract were tentatively identified as α-amyrin, β-amyrin, α-amyrone, and β-amyrone, indicating a botanical affinity of breu canauaru to Burseraceae oleoresins. The volatile oil of the sample showed high levels of limonene (28.3%), δ-3-carene (15.1%), junenol (12.3%), and p-cymene (11.4%), all typical of neotropical Burseraceae oleoresins. The n-alkanes could be either of plant origin, since they are common constituents of waxes, or of animal origin, since they have been previously reported in frog secretions. Therefore, we concluded that our breu canauaru sample primarily originated from the Burseraceae family, although it may also have contributions from other botanical and amphibian sources.
