Summary

Several polyoxygenated steroids (1, 2, 3) have been isolated from the marine gorgonianLeptogorgia sarmentosa. One of these (1) is the known guggulsterol III, previously found in the pharmacologically active resin from the treeCommiphora mukul; the others,2 and3, have not been found before in nature, and are closely related to1. During the structural work apparent anomalies in the CMR-spectra of1 were observed.
