Abstract
Icariin and the complex of icariin metal ion were investigated by electrospray tandom mass spectrometry(ESI MS n). The fragmentation mechanisms of icariin and the possible structure of icariin iron(or aluminium) were proposed. The results showed that icariin and iron (or aluminium) form predominantly a 2∶1 complex.
