A new sarpagine-type alkaloid, Na-methylrauflorine (1), was isolated from Rauvolfia capixabaetogether with isoreserpiline (2),Nb-oxide-isoreserpiline (3), ajmalicine (4), perakine (5) and vinorine (6) alkaloids. These compounds were characterized based on their spectral data basis, mainly one- (1H, 13C, APT) and two-dimensional(1H-1H-COSY, 1H-1H-NOESY, HMQC and HMBC) NMR, and mass spectra, also involving comparison with data from the literature.
