Abstract: Three new acylated flavonoid C-glycosides, 6'''-(-)-phaseoylspinosin (1), 6'''-(3"",4"",5""-trimethoxyl)-(E)-cinnamoylspinosin (2), and 6'''-(4""-O-β-D-gluco-pyranosyl)-benzoylspinosin (3), were isolated from the seeds of Ziziphus mauritiana (Rhamnaceae). A further 19 known compounds including eight spinosin analogues (4-11) were also isolated. Their structures were elucidated by means of spectroscopic analysis and chemical method. Among spinosin derivatives 1, 2, 4, 7, 8, and triterpenoid saponin 14, jujuboside A (14) displayed moderate acetylcholinesterase (AchE) inhibitory activity with an inhibition value of 46.2% at a concentration of 1 μM.
