Quantitative Rhodiola Testing
Rhodiola Glycosides
Scientific-name context: Rhodiola spp. (target occurrence varies by species); Rhodiola rosea (primary rosavin-standardization context)
Rhodiola Glycosides covers 4 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 109
Defined Coverage
One defined quantitative profile
The laboratory will confirm the matrix, reporting basis, sample requirements, timing, and price before testing begins.

Profile Rationale
Useful across Rhodiola species—with species-specific interpretation
The panel may be used for materials labeled as any Rhodiola species. Salidroside is widely distributed across the genus, while rosin, rosarin, and rosavin vary substantially by species and are especially important commercial markers for Rhodiola rosea. They should not be described as the four dominant constituents of every Rhodiola species.
Individual quantitative results support potency, supplier or lot comparison, and review of a species-appropriate specification. Published research has used broader chemical patterns as one part of chemotaxonomic studies, but this four-analyte profile alone does not identify a species or establish a chemotype.
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
Match the glycoside calculation to the specification
Rhodiola specifications may define salidroside and the rosavins differently. Include the exact botanical, material, claim, and calculation language during intake.
Calculation definition
The four-analyte calculated result includes salidroside as well as rosin, rosarin, and rosavin. If a specification instead defines rosavins or phenylpropenoid glycosides from only the latter three, identify that separate calculation before submission.
Botanical and material context
State the labeled Rhodiola species and whether the sample is root or rhizome material, an extract, a blend, or a finished product, and provide the requested reporting basis.
Analytical scope
The four-analyte profile does not by itself establish botanical identity, authenticity, or conformance to a compendial monograph. Share any separate identity or compendial requirement during quote review.
FAQ
Planning a submission
What does Rhodiola Glycosides report?
Rhodiola Glycosides covers the 4 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.
