Pure Resveratrol Powder

Types of Resveratrol

Our company produces three types of the products: micronized resveratrol, resveratrol, and water-soluble resveratrol. We can flexibly provide cosmetic grade, food grade, and pharmaceutical grade of it according to customer needs, supporting one-stop services from sample testing to large-scale supply. In addition, we also support ODM/OEM customized services, providing personalized customization services for different customers to meet their needs to the greatest extent possible.

Different products have different production processes, so the prices are also different. If you are interested in our products, you can contact us via sales@jayuanbio.com and sales1@jayuanbio.com at any time if you feel free.

Micronized Resveratrol

Resveratrol 99%

Water-soluble Resveratrol

Features of Micronized Resveratrol, Resveratrol 99%, and Water-Soluble Resveratrol

1. Micronized Resveratrol: We utilize advanced German-imported NETZSCH airflow milling equipment to achieve particle sizes below 3μm, significantly improving solubility and bioavailability (literature reports indicate particle sizes 2-5 times greater than those of standard powders). This ensures uniform, contamination-free product particles, achieving ultra-fineness control. Low-temperature milling technology effectively protects the active ingredients. Intelligent production utilizes real-time feed rate monitoring to ensure batch stability.

2. Resveratrol 99%: We utilize the latest synthetic biology technology to replace traditional plant extraction, combining supercritical CO₂ purification with AI-powered crystallization control to achieve a breakthrough process with a purity of ≥99.9% and a 40% cost reduction.

3. Water-Soluble Resveratrol: While it is readily soluble in organic solvents such as ethanol and methanol, it is insoluble in water, easily reacts with other chemicals, and exhibits poor light stability. We utilize hydroxypropy-β-cyclodextrin as a key excipient for our water-soluble resveratrol. Its water solubility is significantly better than that of natural cyclodextrin, effectively improving product solubility, bioavailability and stability.

Why Choose Us?

1. Full industry chain control: We have our own planting base and are equipped with advanced German imported airflow crushing equipment to ensure uniform and pollution-free product particles, achieve ultra-fine control, and effectively protect active ingredients with low-temperature crushing technology. Intelligent production monitors the feeding speed in real-time to ensure the stability of batch products. The residual heavy metals and solvents are below international standards, truly achieving integration from raw material cultivation to extraction and purification, reducing intermediate links, and ensuring full traceability of the production process, ensuring cost advantages and controllable prices. Provide customers with stable supply with high cost-effectiveness and support the delivery of large quantities of orders.

2. Standardized production process: We use organic solvent extraction method and select natural sources such as Polygonum cuspidatum and grape skins to ensure high initial active ingredient content (such as resveratrol glycoside in Polygonum cuspidatum ≥ 20%). Reduce physical impurities such as sediment and fibers through pre-treatment steps such as cleaning, drying, and crushing. Select the optimal ethanol with a food grade concentration of 60%~80% and a temperature of 50~70 ℃ (this method is safe, cost-effective, and has a high extraction rate). After concentrating the extract, determine the content of it by HPLC, and then detect ethanol residue by GC to meet ICH standards.

3. Multi stage purification: The first step is to concentrate the crude extract and remove most of the solvent by vacuum distillation. The second part of column chromatography purification uses macroporous adsorption resins (such as AB-8, HPD-100) or silica gel columns to separate the target components. Finally, crystallization and recrystallization are repeated using a solvent (such as methanol/water system) to remove impurities such as pigments and polysaccharides. Terminal purification using Agilent preparative HPLC for the final purification of pharmaceutical grade of it (≥ 99% purity). Using molecular distillation to separate thermosensitive impurities and improve purity. Use nanofiltration to remove trace amounts of macromolecular impurities (such as proteins and colloids). Step by step, effectively improving product purity and bioavailability.

4. Full process monitoring of the production process: Real time monitoring by HPLC, detecting the content of it in key steps such as extraction, concentration, and chromatography to ensure that the purity meets the standard at each stage (such as crude extract ≥ 50%, chromatography ≥ 90%). TLC thin layer chromatography can quickly screen for impurity spots. In terms of process parameter control, it is controlled from three aspects: pH value (such as pH 3-5 during extraction to prevent degradation), temperature (to avoid oxidation caused by high temperature), and pressure (precise regulation during supercritical fluid extraction). Effectively ensure product purity.

5. Impurity analysis and control: Regarding solvent residues, residual amounts such as ethanol and ethyl acetate were detected by GC (in accordance with ICH Q3C standards). For heavy metal residues, atomic absorption spectroscopy (AAS) or ICP-MS is used to detect lead, arsenic, etc. (≤ 10ppm). Pesticide residues are screened using GC-MS/LC-MS for organochlorine and organophosphorus pesticides (compliant with EU MRLs). Heavy metal and solvent residues are strictly controlled to the international pharmacopoeia standards (USP/EP), meeting the high-end demands of pharmaceuticals, health products, and cosmetics.

6. Professional testing report: We use patented purification technology, with a product purity of up to 99% and excellent batch stability performance. At the same time, key indicators such as heavy metals and solvent residues are strictly controlled, and the internal control standards of the enterprise are stricter than those in pharmacopoeias (such as USP/EP). For example, HPLC main peak area ≥ 98% (excluding solvent peaks), Single impurity≤ 0.5% (HPLC normalization method). Support third-party verification and send samples to SGS, Eurofins and other institutions for review. Simultaneously provide COA, heavy metal testing reports, and microbiological testing reports, SGS reports are provided with the goods, and support third-party testing. Realize full traceability from raw materials to finished products, ensuring batch quality stability and cost advantages. Assist customers in achieving maximum profit.

7. Professional testing equipment and personnel: We have five complete GMP standard production lines, a dedicated testing laboratory, and 20 professional testing personnel, providing full cooperation from the base to the workshop to the testing personnel. We are equipped with advanced Agilent and Waters high-performance liquid chromatography (HPLC) detection equipment, Agilent and Thermo Fisher gas chromatography (GC), Shimadzu and PerkinElmer ultraviolet spectrophotometers (UV), and Agilent and Waters mass spectrometry equipment for high-precision qualitative and quantitative analysis. Advanced instrument testing ensures high precision in product quality and purity.

8. Stability and packaging storage: Accelerated testing at 40 ℃/75% RH for 6 months, with regular detection of changes in content (degradation rate ≤ 5%). And long-term testing: 25 ℃/60% RH to determine the shelf life (usually 2-3 years). Store it in an aluminum foil bag or brown glass bottle away from light, lined with a polyethylene bag, sealed with nitrogen for effective moisture resistance, and refrigerated at 2-8 ℃ for long-term storage at -20 ℃. Effectively protect the stability of product performance.
