## Abstract The ^13^C NMR spectra were determined and signals assigned to the various carbons of the alkamines veracevine, germine and zygacine derived from steroidal alkaloids of the ceveratrum class. Assignment of signals was aided by analysis of the partially relaxed spectrum of cervagenine 9,12

The assignments of 13C and 1H NMR spectra for madeirane triterpenes are reported. The assignments were made on the basis of two-dimensional homonuclear 1H, 1H (COSY) and of 1H detected 1H, 13C heteronuclear correlation (HMQC) and also from a series of one-dimensional selective INEPT experiments. 19
