ChemInform Abstract: New Sesquiterpenes from Edible Fungus Clavicorona pyxidata

Three new sesquiterpenes, pyxidatol A–C (1–3, resp.), were obtained from the fermentation culture of Clavaria pyxidata, together with two known ones, tsugicoline E (4) and omphadiol (5). Their structures were elucidated through spectroscopic analyses, including 1D- and 2D-NMR experiments, HR-ESI-Q-TOF mass spectrometry, chemical correlation, and X-ray single-crystal diffraction.
