Isolation and identification of chemical constituents from Albizia julibrissin Durazz

To study the chemical constituents of the stem bark of Albizia julibrissin Durazz.Chemical constituents were isolated by the repeated chromatography methods and their structures were identified by spectral analysis.Five compounds were obtained as follows: 3-O-[beta-D-xylopyranosyl-(1-->2)-beta-D-fucopyranosyl-(1-->6)-beta-D-glucopyranosyl]-21-O-(6S)-2-trans-2-hydroxy-methyl-6-methyl-6-O-beta-D-quinovopyranosyl-2,7- octadienoyl-acacic acid-28 -O-beta-D-glucopyran -osyl(1-->3)-[alpha-L-arabinofuranosyl (1-->4)]-alpha-L-rhamnopyranosyl(1-->2)]-beta-D- glucopyranosyl ester (1). acacigenin B (2) julibrotriterpenoidal lactone A (3) machaerinic acid lactone (4) acacic acid methylester (5).Compound 1 was isolated directly from this plant for the first time.PubMed04421-53
