Abstract:
:Two new xanthone derivatives, penixanthones A (1) and B (2), together with three known compounds, aspenicillide (3), 1,5-dihydroxy-3-methoxy-7-methyl-anthracene-9,10-dione (4) and 1,2-indandiol (5), were isolated from the ethyl acetate extract of a culture of the fungus Penicillium sp. SYFz-1, which was separated from a mangrove soil sample. The structures of these compounds were elucidated by spectroscopic methods including NMR and mass spectrometry. The absolute configurations of penixanthones A (1) and B (2) were determined on the basis of electronic circular dichroism (ECD) data analysis.
