AOAC Method SMPR 2015.009 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Estimation of Total Phenolic Content Using the Folin-C Assay

AOAC SMPR 2015.009 outlines the performance criteria for measuring total phenolic content in dietary supplement products and ingredients using the Folin-Ciocalteu assay. Labs must cover an analytical range of 5–500 ppm (gallic acid equivalents) and ensure a limit of quantitation (LOQ) of ≤5 ppm. Methods must deliver recoveries between 80–110% and demonstrate repeatability (RSDr) ≤9% for 3–5 ppm and ≤7% for higher levels. Reproducibility (RSDR) should stay at or below 13% for 3–5 ppm and 10% for levels above 5 ppm. These specifications help maintain accuracy and consistency across different product types and laboratory setups.
