Simultaneous determination of seven flavonoids in Epimedium by liquid chromatography–tandem mass spectrometry method

In this paper, a sensitive and specific liquid chromatography–electrospray ionisation-mass spectrometry (LC–ESI-MS) method has been developed and validated for the identification and determination of seven flavonoids, namely epimedin A, epimedin B, epimedin C, icariin, sagittatoside B, 2″-O-rhamnosyl icariside II, and baohuoside I in Epimedium from different...
