Reliable Resveratrol Powder Manufacturer & Bulk Supplier

Greenherb operates a controlled extraction facility specializing in Resveratrol Powder. We source Polygonum cuspidatumroots from contracted growing plots, using low-temperature ethanol extraction and recrystallization purification to concentrate trans-resveratrol while controlling cis-isomer conversion. Full export documentation and third-party testing are provided with every batch.

Why Choose Greenherb Resveratrol Powder

● Standardized Trans-Resveratrol Potency – We calibrate trans-resveratrol levels per batch, with customizable assay at 50% and 98% for resveratrol powder supplement formulation lines requiring verified marker density.

● Root-Only Sourcing – Polygonum cuspidatumrhizome material delivers higher native resveratrol content than grape-skin sidestreams, supporting stable bulk pricing.

● Low-Temp Extraction – Sub-50°C ethanol process protects heat-sensitive trans-isomer from converting to cis-resveratrol during processing.

● Recrystallization Purification – Multi-pass recrystallization strips plant pigments and concentrates active content to 98% grade when specified.

● Solvent Residue Compliance – Post-processing solvent checks meet ICH Q3C for global supplement imports.

● Heavy Metal & Pesticide Screening – Multi-point ICP-MS and GC-MS testing ensures compliance with EU/US food-grade standards.

● Mesh Customization – Default 80 mesh, adjustable up to 120 mesh for capsule/tablet line flow optimization.

● Direct Factory Pricing – Transparent quotes for trial batches to full container loads, no distributor markup.

Présentation du produit

Resveratrol Powder is a concentrated botanical extract derived from the roots and rhizomes of Polygonum cuspidatum. Unlike physically ground crude material, this extract isolates and enriches trans-resveratrol via controlled low-temperature solvent extraction and optional recrystallization, delivering a standardized raw material for nutraceutical manufacturers requiring batch-to-batch consistency on the trans-isomer marker.

Processus de production

Greenherb follows a controlled extraction workflow:

Root Sourcing – Polygonum cuspidatumrhizomes harvested at optimal maturity, cleaned and sorted to remove foreign matter.
Crushing – Uniform grinding to optimize extraction surface area.
Low-Temp Ethanol Extraction – Targeted solvent extraction to isolate resveratrol and companion stilbenes.
Purification – Macroporous resin and/or recrystallization steps strip pigments and concentrate trans-resveratrol.
Vacuum Concentration – Solvent recovery under reduced pressure to produce extract paste.
Spray/ Vacuum Drying – Dried to free-flowing crystalline or powdered form depending on target assay.
QC Release – Test trans-resveratrol (HPLC), heavy metals, pesticides, microbiology per batch.
Packaging – Double PE inner + desiccant, nitrogen-flush sealed in fiber drums; 98% grade vacuum-packed for light sensitivity.

Propriétés fonctionnelles et avantages

As a standardized botanical extract, it offers formulation advantages:

● Verified Trans-Isomer – Assay locked on trans-resveratrol via HPLC, not total resveratrol lump sum.

● Grade Flexibility – 50% for blended nutraceutical bases, 98% for premium single-marker SKUs.

● Light-Sensitive Handling – 98% grade vacuum-packed and light-shielded to prevent isomer drift during storage.

● Clean Processing – Solvent residues within global limits, no irradiation or chemical preservatives.

Applications

Resveratrol Powder is engineered for formulation use:

● Nutraceutical Blends – Capsule/tablet fill, powdered antioxidant-themed SKUs for dietary supplement lines.

● Functional Beverage Premixes – Carrier-adjusted grades available for ready-to-mix drink bases.

● Anti-Aging Private Label – Premium 98% grade positioned for beauty-from-within and longevity-themed SKUs.

● R&D Prototyping – Lab samples for formula testing and stability validation.
