| Botanical identity | Confirm the raw material is Rosa roxburghii Tratt. (Roxburgh rose), and clarify whether the extract is made from fruit, seeds, flowers, or another plant part. | Latin binomial and plant-part declaration; raw-material specification; identification method, such as macroscopic or microscopic examination, DNA testing where appropriate, or a validated chemical fingerprint. | Do not accept a common name alone. Different plant parts and related rose species are not interchangeable. |
| Geographic origin | Identify the country and region of cultivation or collection, not merely the location where the extract was processed or exported. | Farm or collection-area records; harvest and receiving records; traceability statement linking the batch to its origin. | Check that the stated origin is consistent across the specification, batch documents, and supply-chain records. |
| Wild collection or cultivation | Determine whether the botanical material is cultivated, wild-collected, or sourced through a mixture of both. | Farm records or collection permits, as applicable; supplier policy on harvest controls; records showing quantities and collection locations. | For wild-collected material, review local permissions and evidence that harvesting is managed responsibly. Do not assume a sustainability claim is verified without supporting records. |
| Harvest and post-harvest handling | Review harvest timing, sorting, drying or stabilization, storage, and transport conditions for the specified plant part. | Documented handling procedures; harvest or processing dates; storage conditions; controls against moisture, pests, and cross-contamination. | Ask how the supplier protects the material between harvest and extraction, and whether the process is consistent from batch to batch. |
| Extract description | Define the extraction solvent, native extract ratio or drug-extract ratio if reported, carrier ingredients, and whether the product is a powder, liquid, or standardized extract. | Technical data sheet; manufacturing flow summary; solvent and carrier declaration; specification stating the measurement basis for any ratio or assay. | Compare products only when plant part, extraction method, carriers, and assay basis are clearly stated. |
| Identity and composition | Set a product-specific identity test and appropriate composition or marker limits; do not assume one universal marker profile for every Roxburgh rose extract. | Batch certificate of analysis (CoA); analytical method; chromatographic fingerprint or justified marker assay, where applicable. | Confirm that results are batch-specific and that the method is suitable for the claimed ingredient and intended use. |
| Contaminant controls | Assess risks relevant to the origin, plant material, extraction process, and intended market, including heavy metals, pesticide residues, microbiological quality, and residual solvents where applicable. | Recent batch CoA with methods, units, and results; risk-based testing plan; laboratory identity and accreditation scope where available. | Check results against the legal and customer limits applicable to the product category and destination market; requirements can differ by use and jurisdiction. |
| Traceability and change control | Confirm that each finished batch can be traced to its incoming botanical material and that changes to origin, plant part, process, or formulation are controlled. | Sample traceability record; batch numbering system; change-control procedure; recall and complaint procedure. | Ask for a documented traceability exercise and notification terms for material changes before placing a long-term order. |
| Quality-system documentation | Review the quality controls relevant to the product's intended category, such as food, supplement, cosmetic, or another application. | Quality-system overview; applicable certifications and current certificates; audit summary or questionnaire; manufacturing and release-control procedures. | Verify certificate scope, site, product category, and validity. A certificate alone does not establish botanical identity or batch quality. |
| Sample and purchase approval | Approve a representative sample against a written specification before production-scale purchasing. | Sealed sample with lot identification; sample CoA; signed specification; agreed acceptance criteria and retest or rejection terms. | Retain an approved reference sample and make the purchase order consistent with the approved specification. |
