The complete assignments of the 1 H and 13 C NMR spectra of the hallucinogenic neoclerodane diterpenoid salvinorin A were determined in three different NMR solvents using HSQC, HMBC and COSY. Solvent systems are described that allow the resolution of all 1 H signals. Virtual coupling was observed for the protons at C‐2, C‐3 and C‐4 in the 600 MHz 1 H spectrum in CDCl 3 . The complete assignments of the 1 H and 13 C NMR spectra of salvinorin B are also reported. Copyright © 2007 John Wiley & Sons, Ltd.
