Brendon D. Gill, Harvey E. Indyk, Maureen C. Kumar, Nathan K. Sievwright, Merilyn Manley-Harris, and Dawn Dowell

A method for the routine determination of 5′‑mononucleotides (uridine 5′‑monophosphate, inosine 5′‑monophosphate, adenosine 5′‑monophosphate, guanosine 5′‑monophosphate, and cytidine 5′‑monophosphate) in infant formula and adult nutritionals is described. After sample dissolution and addition of internal standard, potential interferences were removed by anion-exchange SPE followed by HPLC‑UV analysis. Single laboratory validation performance parameters include recovery (92–101%) and repeatability (1.0–2.3% RSD). The method was approved for Official First Action status by an AOAC expert review panel.
