Chemical constituents from leaves of Albizia chinensis
Objective: To study the chemical constituents of leaves of Albizia chinensis. Method: The chemical constituents were isolated and repeatedly purified with column chromatography. The structures were elucidated by physicochemical properties and spectroscopic methods. Result: Eight compounds were isolated from the 95% ethanol extract of the leaves of A. chinensis and their structures were elucidated as quercetin 3'-O-β-D-glucopyranosyl-3-O-rutinoside (1), kaempferol 3,7-di-O-β-D-glucopyranoside (2),rutin (3), D-pinitol (4), luteolin 7-O-β-D-glucopyranoside (5), ( + )-lyoniresinol 3α-O-β-D-glucopyranoside (6), ( -)-lyoniresinol 3α-O-β-D-glucopyranoside (7), syringin (8). Conclusion: 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.
