DOIAbstract
Seven new azaphilone pigments named lenormandins A-G were isolated from stromata (fruiting bodies) of the xylariaceous fungus, Hypoxylon lenormandii. using preparative High Performance Liquid Chromatography (HPLC) and their structures were elucidated by NMR spectroscopy, high resolution mass spectrometry and other spectral methods. Their occurrence in herbarium specimens (including various type materials collected in the 19th and early 20th century) and several fresh collections was studied by analytical HPLC with diode array and mass spectrometric detection (HPLC-DAD/MS), revealing that this group of pigments is specific for Hypoxylon lenormandii from various geographic regions and otherwise only occurs in closely related taxa, i.e. H. sub...
