Background. An intensive development of the Fast Liquid Chromatography (FLC) has been recently observed. It makes possible to reduce time analysis and improve resolution as well as sensitivity. The aim of this study was to separate the chosen antioxidants optimization using the FLC method. Material and methods. The three various procedures for antioxidants analysis were compared. Mobile phases containing aqueous solution of formie acid, acetic acid, acetonitrile, and methanol were tested. Limit of detection (LOD), limit of quantification (LOQ), linearity and repeatability of each procedures were determined. Results. Developed procedure enabled to separate all analytes and allowed to get low LOD levels and good repeatability. This procedure was used for antioxidants analysis in buckwheat and buckwheat products. Conclusion. Fast Liquid Chromatography allows to reduce time analysis and obtain good validation parameters.

Analysis of pesticide residues was performed by Ultra Performance Liquid Chromatography (UPLC) with Photodiode Array Detector (PDA). Mushroom samples were prepared by acetonitrile extraction. Chromatographic separation was achieved using a BEH C18 analytical column (2.1 mm 􀂰 150 mm), 1.7 μm particle size at flow rate of 0.25 ml/min. Validation studies were carried out on mushroom. In the linear range (0.01 and 0.1 mg/kg) of each pesticide, the correlation coefficient was R2 > 0.99. The relative standard deviation was below 17.1% for all pesticides. The recovery and repeatability of results are in compliance with SANCO/2009 criteria (i.e. average recoveries were in the range 70–120% with RSDs < 20%) for all pesticides The developed method was successfully applied for determination of pesticide residues in mushroom, apple and black currant.
