Quantitative Magnolia Bark Testing
Magnolia Bark Lignans
Scientific-name context: Magnolia officinalis; Magnolia obovata
Magnolia Bark Lignans covers 3 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 117
Defined Coverage
One defined quantitative profile
The laboratory will confirm the matrix, reporting basis, sample requirements, timing, and price before testing begins.

- 01Magnolol
- 02Honokiol
- 034′-O-Methylhonokiol
Profile Rationale
Why these three magnolia bark lignans?
Magnolol and honokiol are generally the principal lignans used to characterize Magnolia officinalis bark and commercial magnolia bark extracts. 4′-O-Methylhonokiol is a prominent, well-characterized third marker that adds composition detail beyond the two compounds most often used for standardization.
Relative concentrations vary by species, plant part, and extract, and magnolia contains additional lignans outside this panel. Cora reports the three measured constituents; the customer defines the applicable ingredient, product, or supplier specification.
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
Define the lignan specification and material context
Share the material type, label claim, intended market, and any constituent-specific limits during intake so the result format matches the project.
Lignan specification
Identify whether limits apply to magnolol, honokiol, 4′-O-methylhonokiol, a combined result, or a separately defined ratio or calculation. Cora reports the results; the customer sets the specification.
Material context
Describe whether the sample is bark material, an extract, a blend, or a finished product and include the 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 Magnolia Bark Lignans report?
Magnolia Bark Lignans covers the 3 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.
