Abstract: Natural abundance¹³C NMR spectra of more than thirty natural Pachysandra alkaloids and their derivatives were recorded. The assignments were made with the help of DEPT technique, based on chemical shifts arguments and comparison with values reported for other related steroidal alkaloids.The application of¹³C NMR spectral analysis for the structure elucidation of Pachysandra alkaloids is discussed.

Key words: Pacbysandra alkaloids, ¹³C NMR, DEPT technique, Chemical shifts
