Product Specifications

What Makes Our Extract Different

Our Polygonum Cuspidatum Extract stands out through three key innovations:

Low-Temperature Extraction Process

Traditional high-heat strategies convert dynamic Trans-Resveratrol into less compelling Cis-form. Our controlled temperature handle keeps up strength through each stage: extraction, nano-membrane separation, concentration, and freeze-drying.

Ultra-Low Emodin Content

Column adsorption chromatography decreases Emodin to underneath 1% or non-detectable levels. This dispenses with undesirable purgative impacts common in standard Polygonum extracts—critical for dietary supplements.

Verified Characteristic Origin

Carbon-14 testing affirms true plant beginning versus cheaper manufactured options made from petrochemicals. Each clump carries a traceable biogenic carbon signature.

Quality Control That Protects Your Brand

Multi-stage testing guarantees each group meets pharmaceutical-grade standards:

Potency Verification

· HPLC examination affirms Trans-Resveratrol content

· Trans-to-Cis proportion checking shows legitimate processing

Safety Screening

· Heavy metals (ICP-MS): Lead, Arsenic, Cadmium, Mercury <10ppm total

· PAH testing: Benzo(a)pyrene <10 ppb per EU Regulation 2015/1933

· Residual solvents: Ethanol <5000ppm per USP <467>

Contamination Prevention

Exclusive sourcing from GAP-certified bases with continuous soil monitoring prevents heavy metal absorption at the root level.

Frequently Asked Questions

Q1: How do you recognize your characteristic extricate from manufactured resveratrol?

Carbon-14 testing confirms biogenic carbon marks one of a kind to plant-derived materials. Manufactured adaptations from petrochemicals need this signature. We conduct intermittent testing to guarantee supply chain integrity.

Q2: What controls the purgative impact caused by Emodin?

Advanced chromatography separates Resveratrol (stilbenes) from Emodin (anthraquinones). Final products contain <1% Emodin or non-detectable levels for sensitive applications.

Q3: Does the bulk powder require special storage conditions?

Yes. Store in double-sealed, light-resistant containers away from direct sunlight and high temperatures. Trans-Resveratrol converts to less-active Cis-form under UV exposure.

Q4: Can this powder work in water-soluble beverage applications?

Standard powder has limited water solubility. We offer water-dispersible grades or technical support for cyclodextrin inclusion complexes to improve dissolution.

Q5: What extraction solvents are used, and are residues a concern?

Only food-grade ethanol and purified water—no toxic solvents like methanol or acetone. Gas chromatography confirms ethanol residues remain <5000ppm per USP <467> standards.
