A simple and rapid method was proposed for the extraction and determination of D-series resolvins produced by head kidney cells from Atlantic salmon. The method involved the use of liquid chromatography triple quadrupole mass spectrometry and a three-level factorial design to optimize the internal standards concentrations. The results suggested that the production of resolvins by head kidney cells might be regulated by circadian responses.
A simple and rapid method for the extraction of D-series resolvins (RvD1, RvD2, RvD3, RvD4, RvD5) released into Leibovitz's L-15 complete medium by head kidney cells from Atlantic salmon and the further determination of liquid chromatography triple quadrupole mass spectrometry is proposed. A three-level factorial design was proposed to select the optimal concentrations of internal standards that were used in the evaluation of the performance parameters, such as linear range (0.1-50 ng mL(-1)), limits of detection and quantification (0.05 and 0.1 ng mL(-1), respectively), and recovery values ranging from 96.9 to 99.8%. The optimized method was used to determine the stimulated production of resolvins by head kidney cells exposed to docosahexaenoic acid, and the results indicated that it is possible that the production was controlled by circadian responses.
