Abstract:

Two new marasmone derivatives, 1α,2β-dihydroxymarasmone(1) and 2β,3α-dihydroxymarasmone(2), and one new norsesquiterpenoid, 14-hydroxyoreadone(3), were obtained from the fermentation broth of Agrocybe sp., together with three known sesquiterpenes, agrocybolacton(4), marasmene(5) and 14-hydroxymarasmene(6). Their structures were elucidated by spectroscopic analyses, including 1D- and 2D-NMR experiments, high resolution electron spray ionization quadrupole time of flight(HR-ESI-Q-TOF) mass spectrometry, chemical correlation, X-ray single crystal diffraction and also compared with reported data.
