摘要：

A novel triterpene, characterized as 6 alpha -hydroxybetulinic acid, was isolated from the leaves and stems of Eugenia moraviana (Myrtaceae), known in Brazil as Cambui, together with three known compounds, platanic acid, betulinic acid and beta -sitosterol. Unequivocal H-1 and C-13 assignments of 6 alpha -hydroxybetulinic acid (3 beta, 6 alpha -dihydroxy-20(29)-lupen-28-oic acid) and platanic acid were undertaken by spectral analysis including NOE and 2 D NMR experiments.
