“…Blood for assessment of salicylate concentration was centrifuged at 3,000 g for 20 min at 4°C, and plasma was stored at –20°C until analysis. Plasma salicylate concentrations were determined by reverse-phase high-performance liquid chromatography [18]. Briefly, liquid-liquid extraction with methylene chloride was used to prepare the sample before injection.…”

“…For the measurement of salicylates, several techniques are 4 available, such as colorimetric, fluorometric, enzymatic, gas or liquid chromatographic assays [14]. Bioanalytical HPLC-UV methods have also been reported for the quantification of ASP and its metabolites [15][16][17][18][19][20][21]. However, the liquid chromatography-tandem mass spectrometry (LC-MS/MS) offers the most sensitive and selective methods for measuring salicylates simultaneously from biological matrices.…”

“…Для предотвращения гидролиза АСК в образцы добавляют неспецифические ингибиторы холинэстеразы, например, фторид калия [15], сни-жают рН и температуру проб [16,17]. Для подготов-ки проб образцов, содержащих АСК, используют методы осаждения белков [16,17], жидкостной [18,19] и твердофазной экстракции [20], а также сочета-ние этих методов.…”
