Polyhydroxylated steroids from the Vietnamese soft coral Sarcophyton ehrenbergi

Steroids, 2021
Fourteen polyhydroxylated steroids including six new compounds, ehrensteroids A - F (1-6), were isolated from the Vietnamese soft coral Sarcophyton ehrenbergi after applying various chromatographic separations. The structure elucidation was done by detailed analysis of 1D, 2D NMR and HR QTOF mass spectra.
