AOAC Method SMPR 2017.010 Instrumentation Guide
Standard Method Performance Requirements (SMPR) for Identification of Aloe Vera in Dietary Supplements and Dietary Ingredients
AOAC SMPR 2017.010 outlines the required performance characteristics for identifying acetylated glucomannan polysaccharides derived from Aloe vera (Aloe barbadensis Miller). This SMPR serves as a reference for compliance under cGMP and ensures that botanical identity is accurately verified in raw materials and finished supplements. The method requires 100% correct identification in the presence or absence of known adulterants, including maltodextrin, gum acacia, carrageenan, and locust bean gum. Laboratories may use chromatographic, spectroscopic, or DNA-based techniques if they can reliably meet the defined selectivity and system suitability expectations. All instruments must support validation procedures that demonstrate specificity, reproducibility, and differentiation from non-Aloe sources.
To meet these rigorous requirements, laboratories can use platforms that enable sensitive carbohydrate detection, detailed chemical fingerprinting, or species-level DNA analysis. HPLC systems with RID detectors offer accurate separation and quantitation of Aloe vera polysaccharides. FTIR platforms support rapid identity verification through unique IR spectral patterns. Real-time PCR instruments allow laboratories to confirm Aloe vera identity at the DNA level, minimizing the risk of misidentification due to visual or chemical similarities. The instruments featured below meet these expectations and are commonly used in the botanical testing industry.
