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.
从与锡矿尾矿相关的真菌培养物中分离出一种新的孕甾类甾体化合物,命名为曲霉醇A(),以及两种已知化合物,(22,24)-麦角甾-5,7,22-三烯-3-醇()和(22,24)-麦角甾-4,6,8(14),22-四烯-3-酮()。借助广泛的光谱分析和电子圆二色性(ECD)光谱的量子化学计算确定了新化合物的结构和绝对构型。
