AOAC Method SMPR 2017.009 Instrumentation Guide

Standard Method Performance Requirements (SMPR) for Quantitation of Aloe Vera Characteristic Water-Soluble Main Constituents in Dietary Supplements

AOAC SMPR 2017.009 outlines the method performance criteria for quantifying key water-soluble constituents of aloe vera, including acetylated glucomannan polysaccharides and degradation products like acetic, malic, and lactic acids. These constituents must be quantified accurately in raw materials, finished products, and freeze-dried liquid samples. Accepted analytical techniques include NMR, GC, GPC, colorimetric methods, and others that meet the method’s performance thresholds. The method requires strict limits of quantitation (LOQ), including ≤0.5% for solids and ≤0.15% for freeze-dried liquids. Recovery must fall between 90–110%, with RSDr ≤10% and RSDR ≤15% across matrices.
