A new pentacyclic triterpene isolated from Myroxylon balsamum (syn. Myroxylon peruiferum)
The new pentacyclic triterpene, 11alpha-methoxy-beta-amyrin (1), was isolated from Myroxylon balsamum (L.) Harms (syn. Myroxylon peruiferum L.f.). Its structure was established on the basis of IR, MS, ¹H NMR, 13C NMR. 2D NMR experiments were also used to establish the structure and the hydrogen and carbon chemical shift assignments of the new triterpene.
