Quantitative Kava Constituent Testing
Kavalactones and Flavokawains
Scientific-name context: Piper methysticum
Kavalactones and Flavokawains covers 9 analytes with individual quantitative results for most raw materials, intermediate ingredients, and finished products.
Standard analysis uses UHPLC-DAD. MS or MS/MS analysis is available for an additional charge when ultra-low detection limits are needed.
Ordering reference: Test Code 104
Defined Coverage
One defined quantitative profile
The laboratory will confirm the matrix, reporting basis, sample requirements, timing, and price before testing begins.

Profile Rationale
Why this profile?
The six major kavalactones are commonly used to characterize kava potency and constituent composition. Reporting each one quantitatively shows the distribution behind the overall result and supports raw-material qualification, extract standardization, supplier comparison, and finished-product verification.
Flavokawains A, B, and C are quantified separately because customers may monitor them in safety-oriented specifications or screening programs. These results provide analytical inputs for a customer-defined safety evaluation; the profile does not by itself determine whether a product is safe.
Method & Reporting
Quantitative results in the reporting basis you need
Standard analysis
The in-house validated method runs standard on UHPLC-DAD. Every analyte listed in the profile is quantitatively reported.
Optional sensitivity
MS or MS/MS analysis is available for an additional charge when a project requires ultra-low detection limits. Confirm feasibility and pricing before submission.
Reporting units
The default unit is w/w%. Results may also be reported as mg/g, mg/mL, or mg/unit when the submission supports the requested basis.
Matrices & Sample Quantity
Raw materials through finished products
Most raw materials, intermediate ingredients, and finished products are supported. Matrix-specific preparation, feasibility, reporting basis, and accreditation needs are confirmed during intake. Call or email the laboratory before submitting less than 2 grams.
Mass-basis reporting
For samples under 2 grams, contact the laboratory before shipping so feasibility can be confirmed.
mg/mL reporting
Send at least 5 mL when results are requested on a volume basis.
mg/unit reporting
Send at least 5 individual units or servings when results are requested per unit.
Turnaround
Five business days standard
Expedited turnaround as fast as 12 hours may be available for an additional fee. Call or email the laboratory for feasibility and the detailed expedite fee schedule.
Have a time-sensitive project?
Include the matrix, sample count, requested reporting units, and deadline so the laboratory can evaluate the fastest available schedule.
Quality Context
Validated in-house
The method is validated in-house. Cora Science is accredited in the field of testing to ISO/IEC 17025:2017 by Perry Johnson Laboratory Accreditation, Inc. (PJLA), Accreditation #116374.
Accreditation applies only to activities listed in the laboratory's current accreditation scope; not every service or matrix is necessarily within scope. State any project-specific accreditation requirement during quote review.
Review quality and accreditation informationMarket & Specification Context
Set the potency and flavokawain specifications before submission
Share the material type, label claim, intended market, reporting basis, and any constituent-specific limits or decision rules during intake.
Kavalactone potency
Identify whether the potency specification applies to one or more individual kavalactones, a combined result, or another separately defined calculation. The six kavalactones are always reported individually.
Flavokawain screening
Provide the customer-defined limits or review criteria for flavokawains A, B, and C. Their quantitative results can inform a safety program but are not a standalone safety determination.
Analytical scope
The quantitative profile does not establish botanical identity, determine safe use, or certify product compliance. Describe whether the sample is raw botanical material, an extract, a blend, or a finished product during quote review.
FAQ
Planning a submission
What does Kavalactones and Flavokawains report?
Kavalactones and Flavokawains covers the 9 analytes listed on this page with quantitative reporting. Share any project-specific specification or reporting convention during quote review.
What matrices can be submitted?
Most raw materials, intermediate ingredients, and finished products are supported. Unusual formats, samples below two grams, and matrix-specific reporting or accreditation requests should be discussed with the laboratory before submission.
What reporting units are available?
The default is weight by weight percent (w/w%). Reporting may also be requested as mg/g, mg/mL, or mg/unit when the submission supports the requested basis.
How quickly are results available?
Standard turnaround is five business days. Expedited turnaround as fast as 12 hours may be available for an additional fee after the laboratory confirms feasibility.
