ABSTRACT
<p><b>AIM</b>To study the bioactive constituents from Anthopleura pacifica.</p><p><b>METHODS</b>Compounds were separated by Pyricularia oryzae bioassay-guided fractionation method with a combination of multi-chromatography. Their chemical structures were determined on the basis of spectral analysis and chemical evidence.</p><p><b>RESULTS</b>A portion showing activity against P. oryzae was obtained and from the portion four compounds were identified as N-hydroxyethyl-N-tetradecanoyl-(2S,3R)-octadecasphinga-4(E), 8(E)-dienine (a), N-hydroxyethyl-N-(9Z-hexadecenoyl)-(2S,3R)-octadecasphinga-4 (E), 8 (E)-dienine (b), N-hydroxyethyl-N-hexadecanoyl-(2S,3R)-octadecasphinga-4(E), 8 (E)-dienine (c) and N-hydroxyethyl-N-(13Z-docosenoyl-(2S,3R)-octadecasphinga-4(E), 8(E)-dienine(d).</p><p><b>CONCLUSION</b>All the four compounds are new ceramides.</p>
