Isolation and identification of chemical constituents from Albizia julibrissin Durazz

To study the chemical constituents of the stem bark of Albizia julibrissin Duraz..Chemical constituents were isolated and their structures identified by the repeated chromatography and spectral analysis.Five compounds were obtained as follows: (-)-Syringaresnol-4-O-beta-D-apiofuranosyl-(1-->2)-beta-D- glucopyranoside (1), (6R)-trans-2,6-dimethyl-6-O-beta-D-quinovosyl-2,7-menthiafolic acid (2), (6S)-trans-2,6-dimethyl-6-O-beta-quinovosyl-2,7-menthiafolic acid (3), 5,5'-dimethoxy-7-oxolariciressinol (4) and (-)syringaresinol (5).Compounds 2, 3 and 4 were new natural products isolated from this plant for the first time.PubMed02180-33
