Chemical constituents from leaves of Albizia chinensis / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To study the chemical constituents of leaves of Albizia chinensis.</p><p><b>METHOD</b>The chemical constituents were isolated and repeatedly purified with column chromatography. The structures were elucidated by physicochemical properties and spectroscopic methods.</p><p><b>RESULT</b>Eight compounds were isolated from the 95% ethanol extract of the leaves of A. chinensis and their structures were elucidated as quercetin 3'-O-beta-D-glucopyranosyl-3-O-rutinoside (1), kaempferol 3,7-di-O-beta-D-glucopyranoside (2), rutin (3), D-pinitol (4), luteolin 7-O-beta-D-glucopyranoside (5), (+)-lyoniresinol 3alpha-O-beta-D-glucopyranoside (6), (-)-lyoniresinol 3alpha-O-beta-D-glucopyranoside (7), syringin (8).</p><p><b>CONCLUSION</b>Compound 1, 2, 4, 6-8 were isolated from this genus for the first time, and compound 3 and 5 were obtained from this plant for the first time.</p>
