β-Sitosterol (24-ethyl-cholest-5-en-3β-ol) and a mixture of five fatty acids have been isolated from the green alga Bryopsis plumosa. The sterol was identified from its proton and carbon-13 NMR spectra and the fatty acids-tetradecanoic acid, hexadecanoic acid. 9- and 11-octadecenoic acids, and octadecanoic acid-were identified from a GC-MS of their methyl esters. The crude extract from B. plumosa demonstrated no activity in either an antimicrobial disk assay or a brine shrimp bioassay for cytotoxicity and was found to be an attractant for the predatory amphipods that were found living on the alga.Copyright 1993, 1999 Academic Press |
