Minor and trace sterols in marine invertebrates 34. isolation and structure elucidation of 24 methyl 5 alpha cholesta 7 9 11 24 28 trien 3 beta ol the first naturally occurring delta 7 9 11 unsaturated marine sterol


, : Minor and trace sterols in marine invertebrates 34. isolation and structure elucidation of 24 methyl 5 alpha cholesta 7 9 11 24 28 trien 3 beta ol the first naturally occurring delta 7 9 11 unsaturated marine sterol. Steroids 39(6): 675-680

The lipid fraction of a Black Sea sponge, Haliclona flavescens, was investigated for its sterol composition. Sterols [23] were identified, including the previously unknown 24-methyl-5.alpha.-cholesta-7,24(28)-trien-3.beta.-ol (3). Identification and structure elucidation was based upon 360 MHz 1H-NMR and mass spectroscopic analyses.
