AOAC Method SMPR 2018.008 Instrumentation Guide
Standard Method Performance Requirements (SMPR) for Determination of Selected Compounds from Teucrium spp. in Skullcap Materials in Commerce
AOAC SMPR 2018.008 outlines the performance requirements for identifying compounds from Teucrium species in skullcap materials. These hepatotoxic compounds, such as teucrin A, must be accurately detected to prevent adulteration in commercial products. The method supports LC-MS and LC-UV instrumentation, though LC-MS/MS systems are preferred for their enhanced selectivity and sensitivity. Analysts must confirm target analytes using consistent retention times and validated MRM transitions. Accuracy and reproducibility must be demonstrated across raw materials, extracts, and finished goods.
Methods must meet strict thresholds for recovery, LOQ, linearity, and repeatability. Instrumentation should maintain calibration linearity (R² ≥ 0.99) while distinguishing Teucrium markers from native skullcap components. Analysts must validate identity using quantifier and qualifier ions with strong signal clarity. The following systems are optimized for such workflows and provide compliance-ready results. These platforms support regulated botanical testing and help ensure product integrity in herbal commerce.
