Isolation of flavonoids and a cerebroside from the stem bark of Albizzia julibrissin

Arch Pharm Res. 2004 Jun;27(6):593-9. doi: 10.1007/BF02980155.

Abstract

From the EtOAc fraction of the MeOH extract of Albizzia julibrissin (Leguminosae), a rare 5-deoxyflavone (geraldone, 1), isookanin (2), luteolin (3), an isoflavone (daidzein, 4), five prenylated flavonoids [sophoflavescenol (5), kurarinone (6), kurarinol (7), kuraridin (8) and kuraridinol (9)], a cerebroside (soya-cerebroside I, 10), and (-)-syringaresinol-4-O-beta-D-glucopyranoside (11) were isolated and characterized on the basis of spectral data. Compounds 2, 3, and 11, showed 1,1-diphenyl-2-picrylhydrazyl radical scavenging activity.
