SPDS Draft SMPR - Ginger
DRAFT AOAC SMPR 2016.XXX; Version 5; November 16, 2016 1 2 Method Name: Quantitation of Select Nonvolatile Ginger Constituents 3 4 Intended Use : Control of incoming ingredients and finished products 5 6 1. Purpose : AOAC SMPRs describe the minimum recommended performance characteristics to be used 7 during the evaluation of a method. The evaluation may be an on‐site verification, a single‐laboratory 8 validation, or a multi‐site collaborative study. SMPRs are written and adopted by AOAC Stakeholder 9 Panels composed of representatives from the industry, regulatory organizations, contract laboratories, 10 test kit manufacturers, and academic institutions. AOAC SMPRs are used by AOAC Expert Review 11 Panels in their evaluation of validation study data for method being considered for Performance 12 Tested Methods or AOAC Official Methods of Analysis , and can be used as acceptance criteria for 13 verification at user laboratories.

2. Applicability :
The method is required to quantitate ‐, ‐ and ‐gingerols and ‐shogaol in the dietary ingredients and dietary supplements listed in Table 2. It is desirable, but optional , for the method to quantitate: ‐ and ‐shogaols, ‐, ‐ and ‐paradols, ‐ and ‐gingerdiols, ‐, ‐ and
‐gingerdiones, and zingerone.
3. Analytical Technique :
Any technique that quantitates the analytes defined in the Applicability statement and satisfies the
method performance requirements set forth in this SMPR.
4. Definitions :
Analytes — Refer to Table 4 for the list of analytes, their chemical attributes and identifiers. Refer to
Figure 1 for the chemical structures.
Dietary Ingredient — A vitamin; a mineral; an herb or other botanical; an amino acid; a dietary substance for use by man to supplement the diet by increasing total dietary intake; or a concentrate, metabolite, constituent, extract, or combination of any of the above dietary ingredients. 1 Dietary
ingredients are conventionally presented as powders or liquids.
Dietary supplement — A product containing a dietary ingredient intended for ingestion to supplement the diet. Dietary supplements containing dietary ingredients are commonly marketed as tablets,
capsules, softgels, tinctures, or other finished dosage forms.
Limit of Quantitation (LOQ) — The minimum content of analyte in a given matrix that can be reliably and precisely quantitated in agreement with the requirements set forth in this SMPR. Repeatability — Statistical variation in the analytical outcome arising when the maximum control over the analytical methodology is afforded. Replicate analyses are performed by the same operator within a short time period using the same instrumentation. Expressed as the repeatability standard
deviation (SD r
) or % repeatability relative standard deviation (%RSD r ).
