Chemical investigation of has led to the isolation of two undescribed compounds, namely 17(20)-dyscusin B () and 17(20)-dyscusin B (), as well as three known ones (-). Structural elucidation was accomplished by the analysis of NMR, MS and IR data. Compounds and were a pair of Δ geometric isomers of pregnane steroids and showed the significant nitric oxide (NO) inhibitory activities.
