摘要
Two flavonol glycoside isomers of Icariside I and Caohuoside C were differentiated by electrospray ionization tandem mass spectrometry (ESI-MS^n) method. In the negative ion mode, the two compounds with different glycosyl moieties showed the same ESI-MS spectrum, but obvious different MS2 spectra and thus they can be distinguished rapidly, accurately and easily by ESI-MS.
