【摘要】 从降香(Dalbergia odorifera)中分离得到10个酚性化合物,运用波谱学方法分别鉴定为dalbergin(1),7-O-methylvestitol(2),syringaresinol(3),3,7-dihydroxy-2’,4’-dimethoxyisoflavanone(4),3’-hydroxy-8-methoxyvestitol(5),2’,6-dihydroxy-4’-methoxy-2-arylbenzofuran(6),3’-O-methylviolanone(7),pinocembrin(8),prunetin(9),mucronulatol(10)。其中化合物1具有乙酰胆碱酯酶抑制活性,化合物2~5为首次从降香中分离得到。更多还原

【Abstract】 Ten phenolic compounds were isolated from Dalbergia odoriferae and purified by repeated column chromatography on silica and Sephadex LH-20 gel,and their structures were identified as dalbergin( 1),7-O-methylvestitol( 2),syringaresinol( 3),3,7-dihydroxy-2’,4’-dimethoxyisoflavanone( 4),3’-hydroxy-8-methoxyvestitol( 5),2’,6-dihydroxy-4’-methoxy-2-arylbenzofuran( 6),3’-O-methylviolanone( 7),pinocembrin( 8),prunetin( 9),and mucronulatol( 10)by spectral analysis. Among these isolates,compound 1 exhibited inhibitory activities against acetylcholinesterase( AChE),and compounds 2-5 were isolated from this plant for the first time.更多还原
