The glycosidic fraction isolated from the seeds of Styrax officinalis L. yielded on acid hydrolysis egonol and a new benzofuran derivative which was formulated as 2-(3.4-dimethoxyphenyl) -5-(3-hydroxypropyl)-7-methoxybenzofuran. EGONOL was isolated by Okadal as an unsaponifiable constituent of the semen-oil of Styrax japonicum Sieb et Zucc; and Kawai et aL2 elucidated its structure and formulated it as 5-(3-hydroxypropyl)-7-methoxy-2-(3,4methylenedioxyphenyl) benzofuran (I).The glycosidic fraction of the seeds of Styrax oficinalis L. yielded after acid hydrolysis and chromatography egonol (I) and two other minor constituents. We describe here the structure elucidation of one of the crystalline minor constituents, for which we propose the formula 2-(3,4-dimethoxyphenyl)-5-(3-hydroxypropyl)-7-methoxybenzofuran (11).The empirical formula C,,H,,05 indicated for compound (11) by analysis was supported by mass spectro-
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
