AOAC Method SMPR 2013.001 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Hypericins, Hyperforins, and Flavonoids in St. John’s Wort (Hypericum perforatum) and Other Hypericum spp.

AOAC SMPR 2013.001 defines the minimum performance requirements for determining hypericins, hyperforins, and flavonoids in dietary supplements and botanical extracts containing St. John’s Wort (Hypericum perforatum) and other Hypericum species. The method allows for the use of different analytical techniques for each class of analytes. Key performance criteria include LOQs ≤ 0.02%, recoveries between 95–105% for low-level concentrations, and reproducibility (RSDR) ≤ 8%. Matrix applicability includes powders, tablets, capsules, and alcohol-based extracts.

Suitable analytical methods must differentiate the target analytes from structurally similar compounds and degradation products. Reliable quantification across 0.05–10% is essential for regulatory compliance. HPLC with UV/PDA detection is commonly used for flavonoids and hypericins, while LC-MS/MS is preferred for hyperforins due to its sensitivity and specificity. The instruments listed below support method compliance when paired with validated workflows and appropriate reference materials. Internal validation is required to confirm performance against SMPR criteria.
