Studies on chemical constituents of green algae Ulva pertusa / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the compounds from Ulva pertusa.</p><p><b>METHOD</b>The alga was extracted with ethanol, isolated and purified by column chromatography on silica gel and sephadex LH -20. All the compounds were identified on the basis of spectral analysis (including IR, MS, NMR).</p><p><b>RESULT</b>Seven compounds were elucidated as cis-asarone (1), trans-asarone (2), gamma-asarone (3), trans-phytol (4), phytyl-stearate (5), phytyl-acetate (6), isophytol (7).</p><p><b>CONCLUSION</b>All other compounds were isolated for the first time from U. pertusa, except for the compound 4.</p>
