ABSTRACT
<p><b>OBJECTIVE</b>To study the chemical constituents of Piper longum.</p><p><b>METHOD</b>The whole plant of air-dried P. longum. was extracted with 95% EtOH. The EtOH extract was suspended in H2O and extracted with petroleum ether, CHC13 and n-BuOH, successively. The compounds were isolated and purified by column chromatography from the CHCl3 fraction, and identified based on spectral analyses (MS,1H-NMR, 13C-NMR).</p><p><b>RESULT</b>Threeteen compounds were isolated from P. longum, and were characterized as 1-(3',4'-methylenedioxyphenyl)-1E-tetradecene (1), 3-(3', 4'-methylenedioxophenyl)-propenal (2), piperoic acid (3), 3',4'-di-hydroxy-biabola-1,10-diene (4), eudesm-4(15)-ene-1beta, 6alpha-diol (5), 7-epi- eudesm-4( 15)-ene-1beta, 6beta-diol (6), guineesine (7), piperine (8), pipericide (9), 2E, 4E-dienamide (10), (2E, 4E, 8E) -N-isobutylhenicosa-2,4,8-trienamide (11), piperlonguminine (12), methyl piperate (13),</p><p><b>CONCLUSION</b>Compounds 1-6 were obtained from P. longum for the first time.</p>
