AOAC Method SMPR 2018.004 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Determination of trans-Resveratrol in Dietary Supplements and Dietary Ingredients

AOAC SMPR 2018.004 outlines the minimum performance requirements for analytical methods quantifying trans-resveratrol in dietary supplements and dietary ingredients. The SMPR applies to raw materials and finished products such as powders, capsules, tablets, softgels, and liquids. Any method used must clearly distinguish trans-resveratrol from cis-resveratrol and related compounds, with a limit of quantitation (LOQ) of 0.01% or lower. Analytical systems must meet precision, recovery, and reproducibility criteria at a range of concentration levels. To meet SMPR 2018.004 compliance, methods must demonstrate a recovery of 90–110%, RSDr ≤ 5%, RSDR ≤ 8%, and linearity of R² ≥ 0.995.

The method allows the use of either HPLC with DAD or LC-MS/MS systems, provided specificity, linearity, and matrix performance criteria are satisfied. Suitable instruments must demonstrate consistent retention time, low background noise, and reliable detection across complex botanical matrices. Each system listed below can support SMPR 2018.004 workflows, assuming proper calibration and validation procedures are implemented. These examples do not imply endorsement by AOAC but represent commonly used platforms in regulated supplement testing. Laboratories should confirm system suitability through in-house validation aligned with AOAC Appendix K and related guidelines.
