[Isolation and identification of chemical constituents from Albizia julibrissin Durazz].
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-[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).


CONCLUSIONS
Compound 1 was isolated directly from this plant for the first time.
