Abstract:
OBJECTIVETo study the chemical constituents of leaves of Albizia chinensis.
METHODThe chemical constituents were isolated and repeatedly purified with column chromatography. The structures were elucidated by physicochemical properties and spectroscopic methods.
RESULTEight 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).
CONCLUSIONCompound 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.
