摘要：

The MeOH extract of the Mediterranean encrusting sponge Oscarella lobularis yielded small amounts of two new polyoxygenated sterols 1 and 2 containing the unique 5α,6α-epoxy-7-keto function. The stereostructures of the two new metabolites were established on the basis of spectral data including 2D nmr experiments. © 1990, American Chemical Society. All rights reserved.
