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.
