The benzofuran constituents of the seeds of Styrax officinalis were investigated. From the hexane extract, two new constituents named 5-(3"benzoyloxypropyl)-7-methoxy-2-(3,4-methylenedioxyphenyl)-benzofuran (5) and 4-[3"-(1c-methylbutanoyloxy)propyl]-2-methoxy-(3',4'-metlhylenedioxvphenyl)- 1a, 5b-dihydrobenzo-[3,4]-cyclobutaoxirene (6) were isolated together with four known compounds, 5-[3"-(1c-methylbutanoyloxy)propyl]-7-methoxy-2-(3',4'-dimethoxyphenyl)-benzofuran (4), 5-[3"-(1c-methylbutanoyloxy)propyl]-7-methoxy-2-(3',4'-methylenedioxyphenyl)-benzofuran (3), 5-(3"-acetoxypropyl)-7-methoxy2-(3',4-methylenedioxphenyl)-benzofuran (2) and 5-(3"-hydroxypropyl)-7-methoxy-2-(3',4-met hylenedioxyphenyl)-benzofuran (1). Although the compounds 1, 2, and 3 have been isolated previously from the seeds of Styrax obassia, this is the first record of their isolation from seeds of Styrax officinalis. The structures of the isolated compounds were established by 1D- and 2D-NMR (HMBC, HMQC, COSY), FABMS and high-resolution ESI FTMS. (C) 2003 Published by Elsevier Ltd.
