AOAC Method SMPR 2017.013 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Determination of Vitamin K1 and K2 in Dietary Supplements and Ingredients

AOAC SMPR 2017.013 outlines the method performance requirements for accurately quantifying vitamin K1 (phylloquinone) and K2 (menaquinones MK-4 and MK-7) in dietary supplements and dietary ingredients. The method requires analytical systems capable of achieving a limit of quantitation (LOQ) of ≤ 0.5 ppm for dietary supplements and ≤ 200 ppm for dietary ingredients. The acceptable analytical range spans from 1 to 3000 ppm for supplements and 1000 to 1,000,000 ppm for ingredients, reported as individual ginsenosides. Recovery must range from 80–110% for low concentrations and 97–103% for higher levels, with repeatability (RSDr) ≤ 11% and reproducibility (RSDR) ≤ 15% depending on the range. Both HPLC and LC-MS/MS systems may be used, provided they meet all criteria for resolution, sensitivity, and validated matrix performance.

Instrumentation must demonstrate excellent linearity, precision, and retention time stability across different product types including softgels, tablets, capsules, and powdered raw materials. External calibration with authentic standards is required, and systems must be capable of separating structurally similar compounds without co-elution. UV/DAD or PDA detectors are suitable when proper peak resolution is achieved, though LC-MS/MS provides enhanced specificity and sensitivity for complex matrices. Below are validated systems from leading manufacturers that fulfill the analytical needs of SMPR 2017.013 when paired with appropriate method validation and sample preparation.
