Abstract
Nocardamine was isolated from an unidentified Streptomyces, species X-14568, and its 1H NMR and 13C NMR spectra are assigned in detail. Reaction with iodomethane and silver oxide converts nocardamine to the tri-O-methyl ether which is a suitable derivative for electron-impact mass spectrometry. Fragmentation mechanisms of tri-O-methylnocardamine are discussed.Keywords
