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。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 '-0-methylviolanone (7), pinocembrin ( 8 ), prunetin ( 9 ), and mucronulatol ( 10 ) by spectral analysis. Among these isolates, compound 1 exhibited inhibitory activities against aeetylcholinesterase (ACHE) ,and compounds 2-5 were isolated from this plant for the first time.
