Abstract:
Objective: To study the chemical constituents of the stem bark of Albizia julibrissin Durazz. Methods: Chemical constituents were isolated by the repeated chromatography methods and their structures were identified by spectral analysis. Results: Five compounds were obtained as follows: 3 O [? D xylopyranosyl (1→2) ? D fucopyranosyl (1→6) ? D glucopyranosyl] 21 O (6S) 2 trans 2 hydroxy methyl 6 methyl 6 O ? D quinovopyranosyl 2,7 octadienoyl acacic acid 28 O ? D glucopyran osyl (1→3) [? L arabinofuranosyl (1→4)] ? L rhamnopyranosyl (1→2) ] ? D glucopyranosyl ester (1). acacigenin B (2), julibrotriterpenoidal lactone A (3), machaerinic acid lactone (4), acacic acid methylester (5). Conclusion: Compound 1 was isolated directly from this plant for the first time.
