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),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.

Key words: Dalbergia odorifera, flavonoids, AChE inhibitory activities
