A new pregnane steroid, named aspergillon A (), together with two known compounds, (22,24)-ergosta-5,7,22-trien-3-ol () and (22, 24)-ergosta-4,6,8(14),22-tetraen-3-one () were isolated from cultures of the tin mine tailings-associated fungus . The new structure and absolute configuration were determined with the help of extensive spectroscopic analyses and quantum chemical calculations of the electronic circular dichroism (ECD) spectra.
