title: [Chemical constituents from ethyl acetate extract of flower of Albizia julibrissin].
abstract: The ethyl acetate extract of the flower of Albizia julibrissin was isolated and purified by silica gel, Sephadex LH-20 and MCI GEL CHP-20P column chromatography to yield 29 compounds. Their structures were elucidated as 8-hydroxy-2, 6-dimethyl-2E, 6Z-octadienoic acid (1), 8-O-formyl-2, 6-dimethyl-2E, 6Z-octadienoic acid (la), 8-hydroxy-2, 6-dimethyl-2E, 6E-octadienoic acid (2), 8-O-formyl-2, 6-dimethyl-2E, 6E-octadienoic acid (2a), (2E, 6S)-2, 6-dimethyl-6-O-beta-D-xylpyranosyloxy-2, 7-menthia-folic acid (3), clovan-2beta, 9alpha-diol (4), 2beta-O-formyl-clovan-9alpha-ol (4a), 2beta, 9alpha-O-diformyl-clovan (4b), vomifoliol (5), (6S, 9R)-roseoside (6), vanillin (7), 4-O-ethylgallic acid (8), 3-ethoxy4-hydroxy-benzoic acid (9), p-hydroxybenzaldehyde (10), gallic acid (11), protocatechoic acid (12), stearic acid (13), palmitic acid (14), 2, 3-dihydroxypropyl hexadecanoate (15), linoleic acid (16), scopoletin (17), indole-3-carboxaldehyde (18), 2-furoic acid (19), 5-(hydroxymethyl)-2-furaldehyde (20), (22E, 24R)-5alpha, 8alpha-epidioxy-ergosta-6, 22-dien-3beta-ol (21), (22E, 24R)-5alpha, 8alpha-epidioxy-ergosta-6, 9, 22-trien-3beta-ol (22), (+)-lariciresinol 9'-stearate (23), formononetin (24) and uridine (25). Compounds 1a, 2a, 4a and 4b were new artifacts from the separation process, and others were obtained from A. julibrissin for the first time.
