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.
