title: 2-aryl benzofurans and their derivatives from seeds of Styrax macranthus.
abstract: Two new 2-aryl benzofuran derivatives, 3-[7-methoxy-2-(3,4-methylenedioxyphenyl) benzofuran-5-yl]propyl 3-[7-methoxy-2-(3,4-methylenedioxyphenyl)benzofuran-5-yl]propanoate (1) and demethoxy egonol gentiobioside (2), were isolated from the aqueous ethanolic extract of the seeds of Styrax macranthus, together with 7-methoxy-2-(3,4-methylenedioxyphenyl)benzofuran-5-carbaldehyde, egonol, demethoxy egonol, demethyl egonol, egonol glucoside, egonol gentiobioside, egonol gentiotrioside, stigmasterol, 2,3-dihydroxypropyl tetracosoate, and daucosterol. Their structures were elucidated on the basis of spectral and chemical evidence.
