COSTA, Túlio de Orleans Gadelha et al. Chemical constituents from the stem of Protium hebetatuml (Burseraceae). Acta Amaz. [online]. 2012, vol.42, n.4, pp. 557-560. ISSN 0044-5967. http://dx.doi.org/10.1590/S0044-59672012000400014.
Protium is the largest genus in the Burceraceae family, which comprises about 146 species, of which a small number has been studied from the phytochemical point of view. In this work the terpenoids α- and β-amyrin, the steroids campesterol, stigmasterol and sitosterol and the coumarin scopoletin were isolated from the stem of Protium hebetatuml. The structures of these substances were identified by NMR, MS, IV and comparison with spectral data from the literature and with authentic samples.
