Abstract:

An ultra-performance liquid chromatography-mass spectrometry method (UPLC-MS) was developed for the simultaneous determination of four pyridine nucleotide coenzymes (NADPH, NADP+, NADH and NAD+) in cells. The analytes were rapidly extracted with methanol at low temperature, separated by Atlantis PREMIER BEH C18AX column with a gradient elution with 10 mmol/L ammonium formate and acetonitrile, and detected in negative ion [M-H] -scanning under the multiple reaction monitoring (MRM) mode. For the four pyridine nucleotide coenzymes, the method shows good linear relationships in wide ranges of concentrations, the limits of detection and quantification are in the range of 0.03~0.3 pmol and 0.06~1.2 pmol, respectively, and the detection accuracy is 92.71%~107.65% with the relative standard deviation of 1.98%~7.57%. The method is simple, rapid, accurate and sensitive. It is suitable for the rapid quantitative determination of pyridine nucleotide coenzymes in both human and microbial cells, and provides reliable technical support for the research of cell physiological metabolism.
