Five flavone C-glycosides were isolated from the methanol extract of the degrease seeds of Ziziphus jujuba var. spinosa though various column chromatography methods including silica gel, MPLC, and HPLC. The structures were elucidated as 6"-feruloyl- 6'''-vanillylspinosin(1), 6",6'"-diferuloylspinosin(2), spinosin(3), swertisin(4) and isoswertisin(5) based on the NMR and MS spectral data. 1 is a new compound.
