OBJECTIVE
To study the chemical constituents of Chinese medicine Acacia catechu.
METHODS
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.
RESULTS
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).
CONCLUSIONS
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.
