AOAC Method SMPR 2017.016 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Determination of SAMe in Dietary Ingredients and Dietary Supplements

AOAC SMPR 2017.016 defines method performance requirements for determining S-Adenosyl-L-methionine (SAMe) in dietary ingredients and finished products. It specifies the quantification of total SAMe with a required analytical range from 5 to 800 mg/g and a limit of quantitation (LOQ) of ≤ 1 mg/g. The method must differentiate the active S,S-diastereomer from other isomers and degradation products. Accuracy must be maintained between 90–110% for ≤ 15 mg/g and 98–105% for > 15 mg/g. Repeatability (RSDr) should be ≤ 8% for lower concentrations and ≤ 5% for higher concentrations, while reproducibility (RSDR) should remain ≤ 10% and ≤ 8%, respectively.

Instruments used for this analysis must deliver strong chromatographic resolution, low carryover, and excellent retention time stability. Both LC-MS/MS and UV-based HPLC systems are permitted if they fulfill AOAC’s precision, recovery, and quantitation criteria. Labs should use method-specific validation protocols to verify compliance with the performance standards. Systems must also ensure minimal interference from closely eluting impurities or matrix components. The following platforms have demonstrated reliable performance when configured for SAMe detection in capsules, tablets, and powder supplements.
