Resumo: From the hexane extract from stem bark of Rauwolfia mattfeldiana Markgr. (Apocynaceae) a new depside (1, methyl 4’-O-methylarthonioate), along with 1-hydroxy-3,6-dimethoxy-8-methylxanthone (4), lupeol (5), sitosterol (6) and stigmasterol (7) were isolated. The structures of these natural products were elucidated by spectral data analysis. 2D NMR experiments were used to establish the structure and the complete hydrogen and carbon chemical shift assignments of the new depside.
