Chemical investigations of the marine-derived fungus Verticillium tenerum yielded two new hydroxylated bisabolane-type sesquiterpenes verticinol A (1) and B (2). The planar structures of the new compounds were elucidated by employing spectroscopic (NMR, UV, and IR) and mass spectrometric techniques. The absolute configuration of the cyclohexenyl moiety was deduced by a combination of CD spectroscopy and NOESY measurements.
