摘要: Two new ergostane-type steroids (1 and 2) have been isolated from the fruiting body of a medicinal macro fungus Ganoderma lingzhi. The structures including the absolute configurations of them were elucidated by a combination of different spectroscopic analyses especially C-13 NMR and ECD calculations. Compound 2 features an unusual 1,2-dioxolane moiety. Our bioassays revealed that the two steroids showed remarkable cytotoxicity against human A549 (lung) and MCF-7 (breast) tumor cell lines, with IC50 values ranging from 5.15 to 8.57 mu g/mL.
