Product forms for your application
Our quotation range covers the material forms below. We confirm the available grade, concentration and sample terms in your quotation.
On small screens, scroll within the table.
| Form | Composition | Application fit |
|---|---|---|
| Purified trans-resveratrol powder | Trans assay, cis/related compounds and source declared | Dry blending and encapsulation projects |
| Knotweed-derived extract option | Resveratrol, polydatin and source impurities distinguished | Botanical ingredient formulas |
| Carrier-based formulation option | Active loading and full carrier composition declared | Reconstitution or topical development |
Specifications, assay methods & quotation basis
| Item | Quotation & acceptance basis |
|---|---|
| Identity & composition | Trans-resveratrol · source, production route and purification specified by grade · State ingredient composition, source route, carriers and relevant processing aids. |
| Markers & methods | The requested trans-resveratrol specification uses an agreed HPLC method that distinguishes cis isomer and relevant related substances, with dry or as-is basis stated. Polydatin is reported separately from free resveratrol. |
| Physical & handling properties | Agree colour, odour, moisture, particle size and dissolution or dispersion requirements for the selected form, rather than one limit for every grade. |
| Contaminants & release | Agree microbiological, pesticide, elemental-impurity and residual-solvent scope and limits by source, process and market. Batch COA values must correspond to actual results. |
Why buy resveratrol from ZL Botanicals?
Competitive bulk pricing
Competitive resveratrol pricing separates purified powder, botanical extract and carrier-based options by trans content and supplied composition.
Quality for repeat purchasing
Trans-isomer identity, related-substance controls and carrier loading give repeat resveratrol orders a defined acceptance basis.
Certification-document support
Resveratrol qualification support ties source and production-route records to the selected material and intended market.
Reliable delivery coordination
Resveratrol sample and bulk planning includes the chosen form, light-protective packaging requirements and written delivery terms.
Quality control, COA & certification documents
Knotweed-origin material needs source-specific impurity controls, including an agreed emodin requirement. Synthetic-material assessments do not automatically qualify botanical extracts.
TDS defines the specification, COA records the identified batch, and SDS supports safe handling. We coordinate documents for the project and review certification needs against material, holder, site, scope and validity. Include GMP, ISO, Halal, Kosher or organic requirements in the enquiry; these are not blanket certifications for every product.
Application formats & sample evaluation
Poor water solubility makes loading, crystallization and light/oxygen stability important. A dispersion concept is not evidence of improved clinical absorption or longevity.
These are development concepts, not customer cases, validated formulas or finished-goods manufacturing offers. Confirm intended use for the material and target market.

We quote against selected form, assay and method, volume and destination. Your written quotation includes sample quantity and cost, MOQ, pack size, storage conditions, shelf-life or retest basis, lead time, Incoterms and payment terms.
Once the sample and order specification are agreed, record acceptance criteria, batch documents and change-notification terms for repeat purchasing.
Request pricing by volume & destination →Resveratrol purchasing FAQ
Is resveratrol another name for grape seed extract?
No. Resveratrol is a named molecule; grape seed extract is a different mixture. We keep source, trans assay and carrier loading explicit in the quotation.
How are samples, prices and minimum orders confirmed?
Send the target specification, application, first-order quantity and destination. We respond with sample availability and a quotation for the selected material; quantity, cost, documents and delivery terms are confirmed in writing.
Which quality and certification documents can I request?
Enquire about TDS, the relevant batch COA, SDS and project-specific certification documents. Actual documents are coordinated by material and use, with certificate scope reviewed separately. This page is not a batch test report.
