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.

Method of high-resolution time-of-flight mass spectrometry combined with high performance liquid chromatography has been developed for the detection and determination of residues of 23 quinolones (fluoroquinolones) and a number of sulfonamides in foods. The samples were prepared using simplified and quick sample preparation. The limits of detection of quinolones and sulfonamides ranged from 0.05 (1) to 1000 (2000) mkg kg‒1. A scheme for identification and determination of detected quinolones has been developed using method of standard addition. The relative standard deviations of analysis results are less than 0.1.
