A new chamigrane sesquiterpene, albocimea A ( 1 ), and one known compound, 6-hydroxy-8-methoxy-3 S ,5-dimethylisochroman ( 2 ), were isolated from the rice fermentation of the fungus Antrodiella albocinnamomea . The structure of new compound was elucidated by extensive spectroscopic analyses and electronic circular dichroism (ECD) calculations. Both compounds were evaluated for their cytotoxicity against five human cancer cell lines, but no significant cytotoxicity was found (IC 50 values > 40 μM).

One new sterpurane sesquiterpene ( 1 ), named (3 R ,6 S ,7 S ,8 R ,10 S )-3,7,14-trihydroxy-1-sterpurene was isolated from cultures of the basidiomycete Pholiota nameko. The structure of new compound was elucidated by extensive spectroscopic. Additionally, a single crystal X-ray diffraction not only confirmed the structure, but also determined the absolute configuration of the new compound. The compound was evaluated for cytotoxicity against five human cancer cell lines, but no significant cytotoxicity were found (IC 50 values > 40 μM).

Two new sesquiterpenes ( 1-2 ), along with one known sesquiterpene ( 3 ), were isolated from cultures of the higher fungus Pholiota nameko. The structures of new compounds were elucidated by extensive spectroscopic methods. The known compound was identified by comparing its spectroscopic data with those reported in the literature. All compounds were evaluated for their cytotoxicities against five human cancer cell lines.
