  • 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 [soph6f1avescenol (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.
