Quantitative Ashwagandha Testing
Ashwagandha Withanolides
Ashwagandha Withanolides covers 6 analytes with quantitative reporting across all matrices, plus Panel Sum as a calculated value.
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 105

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, and Panel Sum is reported separately as a calculated value.
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
Available for all matrices
Matrix-specific preparation and reporting needs are reviewed 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
Match the reported result to the specification language
Ashwagandha specifications may use different constituent lists and calculation definitions. Include the exact claim or specification language during intake.
Calculation definition
This profile reports Panel Sum as a calculated value. If a specification requests another defined constituent calculation, identify the exact convention before submission.
Material context
Describe whether the sample is root, leaf, an extract, a blend, or a finished product and provide the label claim and requested reporting basis.
Analytical scope
The quantitative profile does not by itself establish botanical identity or certify product compliance. Share any separate identity or market requirement during quote review.
FAQ
Planning a submission
What does Ashwagandha Withanolides report?
Ashwagandha Withanolides covers the 6 analytes listed on this page with quantitative reporting. It also reports Panel Sum as a calculated value. Share any project-specific specification or reporting convention during quote review.
What matrices can be submitted?
The profile is available for all matrices. Unusual formats, samples below two grams, and matrix-specific reporting 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.
