Abstract:
Objective: To study the chemical constituents from 70% ethanol extract of Ziziphi Spinosae Semen. Methods: Five compounds were isolated and purified by macroporous resin D101, silica gel, Sephadex LH-20, Toyopearl HW-40, and ODS column chromatographies. Results: Five compounds (1-5) were isolated from 70% ethanol extract of Ziziphi Spinosae Semen. Their structures were identified by spectroscopic methods, as 6″, 6‴-diferuloylisospinosin (1), kaempferol-3-O-β-D-xylopyranosyl-(1→2)- [α-L-rhamnopyranosyl-(1→6)]-β-D-glucopyranoside (2), spinosin (3), isospinosin (4), and 6‴-feruloylspinosin (5). Conclusion: Compound 1 is a new flavone C-glycoside named 6″, 6‴-diferuloylisospinosin. Compound 2 is reported from the genus Ziziphus Mill. for the first time.
