| Abstract: | Objective: To study the chemical constituents of Chinese medicine Acacia catechu. Method: Isolation and purification were carried out on normal phase silica gel, Sephadex LH-20, ODS column chromatography etc. Constituents were identified by physicochemical properties and spectral analysis. Result: Twelve compounds were identified as 4-hydroxybenzoic acid( 1 ), kaempferol( 2 ), quercetin( 3 ), 3,4',7-trihydroxyl-3',5-dimethoxyflavone( 4 ), catechin( 5 ), epicatechin( 6 ), afzelechin( 7 ), epiafzelechin( 8 ), mesquitol( 9 ), ophioglonin ( 10 ), aromadendrin( 11 ), and phenol ( 12 ). Conclusion: Compounds 7, 12 were isolated from A. catechu for the first time, and compounds 4, 9-11 were isolated from the genus Acacia for the first time. |
