[HPLC-ESI-MS(n) analysis of chemical constituents in Semen Ziziphi Spinosae].
OBJECTIVE
To study on the chemical constituents of effective part of Semen Ziziphi Spinosae.


METHODS
The sample was extracted with methanol and purified by macroporous resin. The structures were identified by high performance liquid chromatography/electrospray ionization with multi-stage tandem mass spectrometry.


RESULTS
Thirteen compounds were identified from the effective part of Semen Ziziphi Spinosae.


CONCLUSIONS
The method is simple and rapid for the identification of the flavonoids and triterpenoid saponins from Semen Ziziphi Spinosae.
