Interpretive Summary: This paper describes AOAC Standard Method Performance Requirements (SMPR) for the quantitation of phenolics in dietary supplement raw materials (ingredients) and finished products for Echinacea species. Authors following chair listed alphabetically.

Technical Abstract: This AOAC Standard Method Performance Requirements (SMPR) is for authentication of Echinacea phenolic compounds in dietary ingredients and supplements. SMPRs describe the minimum recommended performance characteristics to be used during the evaluation of a method. The evaluation may be an on-site verification, a single-laboratory validation, or a multi-site collaborative study. SMPRs are written and adopted by AOAC stakeholder panels composed of representatives from industry, regulatory organizations, contract laboratories, test kit manufacturers, and academic institutions. AOAC SMPRs are used by AOAC expert review panels in their evaluation of validation study data for methods being considered for Performance Tested Methods or AOAC Official Methods of Analysis, and can be used as acceptance criteria for verification at user laboratories.
