摘要
Three new diarylpropanes were isolated from the dried rhizomes of Dioscorea composita Hemsl., and their structures were determined as 1, 3-bis-(2-hydroxy-4-methoxyphenyl) propane (1), 1, 3-bis-(2, 4-dihydroxyphenyl)propane (2), 1-(2′-hydroxy-4′-O-β-D- glucopyranosy- phenyl)-3-(2′′, 4′′-dihydroxyphenyl)propane (3), by spectroscopic analysis, respectively.
