Abstract

Four peptaibols, named trichokonins (TKs) V, VI, VII, and VIII, were isolated from the culture broth of Trichoderma koningii OUDEMANS. Primary structures of these peptaibols were elucidated by electrospray ionization mass spectrometry (ESI-MS), FAB-MS and collision-induced dissociation (CID) techniques along with nuclear Overhauser enhancement spectroscopy (NOESY).
