Résumé
<p><b>OBJECTIVE</b>To investigate the chemical constituents from the aerial parts of Breynia fruticosa.</p><p><b>METHOD</b>Various chromatographic techniques were employed for isolation and purification of the constituents. The structures were elucidated by chemical evidence and spectral methods.</p><p><b>RESULT</b>Seven compounds were obtained and identified by spectroscopic methods and compared with authentic samples as aviculin [(+)-isolariciresinol-9'-rhamno-pyranoside], friedelan-3beta-ol, friedelin, arborinone, isoarborinol, 5-hydroxy-7,8,4'-trimethoxy flavone, 2,4-dihydroxy-6-methoxy-3-methyl-acetophenone.</p><p><b>CONCLUSION</b>All compounds were firstly isolated from B. genus, furthermore, aviculin was isolated from Euphorbiaceae for the first time.</p>
