- Abstract
- Two benzofurans (1, 2) along with five known compounds (3.7) were isolated from the seeds of S. obassia. Their structures were elucidated as methyl 3-[7-methoxy-2-(3',4'-methylenedioxyphenyl)-5-benzofuranyl]-propionate (1), methyl 3-[2-(3',4'-methylenedioxyphenyl)-5-benzofuranyl]-propionate (2), egonol (3), egonolacetate (4), egonol-2-methylbutanoate (5), 7-demethoxyegonol-2-methylbutanoate (6), and stigmasterol (7) on the basis of their comprehensive spectroscopic analysis including 2D NMR data. Compounds 1, 2 are obtained for the first time from nature, while this is the first record of compound 7 from the Styrax species.
