High-Purity Polygonum Cuspidatum Extract Powder | 98% Resveratrol for Anti-Aging & Functional Foods

Premium Polygonum Cuspidatum Extract powder is produced by Shaanxi Zhenhuacui Biotechnology Co., Ltd. utilizing sophisticated spray drying and supercritical CO₂ extraction methods. Our flagship extract yields 98% HPLC-verified trans-resveratrol for unparalleled purity and stability in demanding industrial applications. We guaranty batch-to-batch performance with over 10 years of production expertise and a cGMP, FSSC22000, and HACCP-certified quality system. The extract is tested for emodin elimination (<5ppm) and PAH4 compliance to fulfill worldwide regulations. Our factory has enough inventory for 1 kilogram orders, with normal delivery in 10 days and expedited green channel service in 7–10 days.

Product Descriptions

Our resveratrol and polydatin extract comes from real Polygonum cuspidatum rhizomes extracted under regulated conditions. The light brown powder is soluble and compatible with many dose forms.

The advanced extraction process preserves bioactive stilbenoids while eliminating anthraquinone contaminants. Micronization technology enhances bioavailability, addressing the compound's natural absorption limitations.

Application Areas

Our product benefits three key industries:

Anti-Aging Supplements

Sirtuin-activating capsules and liposomes. AMPK signaling modulation can be used to create mitochondrial support products for energy metabolism.

Cosmetic Skincare

Brightening serums and UV creams include it. Hyperpigmentation therapies benefit from its tyrosinase inhibition, while photo-aging prevention formulations benefit from its collagen protection.

Functional Drinks

Fortified beverages stay clear with water-soluble grades. Without precipitating active chemicals, your manufacturing team may pasteurize complicated multi-ingredient matrices.

Benefits 

Superior Antioxidant Activity

Cis-isomers neutralize reactive oxygen species less than trans-resveratrol. Increased oxidative stress protection for cardiovascular and liver health in your formulations.

Purity for Clinical Use

98% concentration permits capsule micro-dosing. Reduce excipient mass to provide room for supplementary actives in multi-ingredient blends.

Excellent Stability

Controlled storage and vacuum-sealed packing avoid oxidation. Your inventory stays potent for 24 months under prescribed circumstances.

Compliance with regulations

Your supplements fulfill EU and FDA standards with PAH4 and emodin testing. Costly market entry reformulation delays are avoided.

Quality Control 

Three-Stage Testing Protocol

Checking Raw Material

The botanicals are microscopic identified and heavy metal screened.

During Monitoring

Spray drying HPLC analysis tracks resveratrol concentration hourly. Within ±1% tolerance, real-time modifications preserve the 98% specification.

Complete Release Testing

Labs verify microbiological safety (>1,000 cfu/g), solvent residues (<10 ppm), and polycyclic aromatic hydrocarbons (EU limits). Every package comes with an analysis certificate.

COA

Each batch includes a comprehensive Certificate of Analysis documenting:

· Resveratrol content (HPLC chromatogram)

· Emodin levels (UV-Vis spectrophotometry)

· Heavy metals (ICP-MS: Pb <2 ppm, As <1 ppm)

· Microbial counts (E. coli: Absent, Salmonella: Absent)

· Moisture content (<5%)

· Particle size distribution (D90 <100 µm)

We provide COA templates during the quotation stage so your regulatory team can pre-approve specifications.

Packaging and Transportation

Primary Packaging

Food-grade aluminum foil bags with nitrogen flushing prevent oxidation. Each 25 kg fiber drum includes desiccant packs and tamper-evident seals.

Shipping Options

· Express (DHL/FedEx): 3–5 days for samples and urgent orders

· Air Freight: 7–10 days for bulk orders under 500 kg

· Sea Freight: Cost-effective for container loads (20+ tons)

R&D Results

Our research team has improved resveratrol delivery techniques. Some recent projects:

Technology Microencapsulation

FAQ

Q: Why trans-resveratrol over cis?

A: SIRT1 activation is confirmed in trans-resveratrol. It outperforms the cis-form in stability and clinical effectiveness.

Q: How to avoid powder discolouration during storage?

A: Oxidation turns pink or brown. Store in vacuum-sealed aluminum containers below 25°C and out of direct light. Nitrogen-flushed packaging preserves color for 24 months.

Q: What distinguishes 98% and 50% resveratrol for formulation?

A: 98% works for low-excipient micro-dose capsules and beauty serums. Whole-herb marketers wanting "closer-to-nature" positioning choose 50%'s plant matrix.
