An approach for simultaneous detection of icariin, icaritin, icarisides I, II, epimedins A, B, C in extracts from plants and сommегсial pгoduсts was developed on the basis of liquid chromatography/mass spectrometry. Using the dry and liquid extracts of Epimedium and the tea, the validation of the approach was carried out. Limits of detection were 5×10−4 mkg ml−1. For compounds determination, electrospray ionization in positive ion mode and tandem mass spectrometric detection in multiple reaction monitoring mode were used.
