Gensei High-Purity Extraction Process

Raw Material Preparation

Selection of premium Polygonum cuspidatum roots. Washing, drying, and coarse grinding to increase surface area for extraction.

↓

Solvent Extraction (Reflux)

Multi-stage reflux extraction using Food Grade Ethanol/Water mixture. This gentle process protects the bioactivity of resveratrol.

↓

Concentration & Filtration

Vacuum evaporation to recover ethanol solvent. The liquid extract is filtered to remove plant fibers and insolubles.

↓

Purification (Chromatography)

Critical Step: Passing through macroporous resin columns to separate Trans-Resveratrol from impurities like Emodin and sugars.

↓

Crystallization & Centrifugation

Controlled cooling to form high-purity crystals. Centrifugation separates the crystals from the mother liquor.

↓

Vacuum Drying

Low-temperature drying under vacuum conditions to prevent oxidation and ensure low solvent residue (< 5000ppm).

↓

Milling & Sieving

Micronization to achieve standard particle size (95% pass 80 mesh) for uniform blending in supplements.

↓

Final QC & Packaging

Comprehensive testing (HPLC Assay, Heavy Metals, Microbes). Packed in double LDPE bags inside fiber drums.

Applications & Solutions

Superior Color Control: Many suppliers offer 98% resveratrol that is still slightly beige. Gensei utilizes advanced recrystallization technology to achieve a resveratrol white powder that meets the strict aesthetic requirements of luxury skincare brands.
Guaranteed “Trans” Isomer: We strictly control the conversion process to ensure the product is predominantly Trans-Resveratrol, the bioactive form, rather than the inactive Cis-form.
Reliable Manufacturer: As a professional resveratrol powder manufacturer, we have full traceability from the raw herb (Polygonum cuspidatum) to the finished drum.
Safety First: Our extraction process minimizes Emodin (a laxative compound found in the raw plant) to safe, trace levels (<0.1%), preventing digestive side effects in end consumers.
