Extracts China offers premium Polydatin Powder, a highly active natural plant extract meticulously derived from the dried roots and rhizomes of Polygonum cuspidatum (Japanese Knotweed). As a leading botanical extract ingredient, Polydatin (also known as piceid) is a glycosylated derivative of resveratrol.
From a formulation perspective, Polydatin Powder presents distinct advantages over standard resveratrol. The glycoside moiety significantly enhances its water solubility, chemical stability, and overall antioxidant capacity. Furthermore, advanced phytopharmacological studies indicate that Polydatin demonstrates superior bioavailability and more potent anticancer effects compared to its parent compound, resveratrol, making it a highly sought-after raw material for advanced dietary supplements and nutraceutical formulations.
Botanical Profile and Nutritional Composition
Polygonum cuspidatum, a member of the Polygonaceae family, boasts a long-standing history in traditional herbal medicine. The plant is a rich matrix of bioactive phytochemicals. Beyond the primary active compound polydatin, the botanical source contains a complex profile of beneficial constituents, including:
- Resveratrol glycosides and emodin derivatives (emodin methyl ether, chrysophanol, anthracene glycoside A and B, charming alcohol, 6-hydroxyaloe-emodin, and emodin-8-methyl ether).
- Flavonoids and phenolic compounds such as protocatechin, dextrocatechin, 2,5-dimethyl-7-hydroxychromone, and 7-hydroxy-4-methoxy-5-methylcoumarin.
- Additional micronutrients including β-sitosterol glucoside, cassia-8-glucoside, polysaccharides, essential amino acids, and vital mineral salts (copper, iron, manganese, zinc, and potassium).
This diverse phytochemical profile ensures a synergistic environment for the primary active ingredient, maximizing the functional benefits of the final extract.
Physical and Chemical Properties
For formulation scientists and raw material purchasers, understanding the chemical behavior of Polydatin Powder is crucial for product development.
- Appearance: White, needle-like crystalline powder.
- Solubility: Easily soluble in ethanol, methanol, chloroform, and acetone. Practically insoluble in water (0.03g/L). Solubility in ethanol is significantly higher (50g/L).
- Stability: Unstable under alkaline conditions (pH > 10), where it will undergo a color change to pink or red. Formulators should maintain acidic to neutral pH environments to preserve ingredient integrity.
- Spectral Properties: Exhibits maximum ultraviolet absorption and fluorescence at 366nm, a characteristic utilized for analytical quantification and quality control.

Functional Benefits and Modern Pharmacological Value
In traditional herbal practice, Polygonum cuspidatum is recognized for its slightly bitter taste and cold nature, traditionally utilized to dispel wind and dampness, disperse blood stasis, alleviate pain, and resolve phlegm. Modern pharmacological research heavily validates these traditional uses, confirming that Polydatin exhibits comprehensive antioxidant, anti-inflammatory, antitumor, antibacterial, and immunomodulatory effects.
Cardiovascular and Metabolic Health
Polydatin Powder is widely incorporated into cardiovascular support formulas. It functions by strengthening heart muscle contraction, expanding blood vessels, and inhibiting platelet aggregation. Furthermore, it plays a regulatory role in blood lipid profiles, making it highly applicable in supplements targeting metabolic syndrome and cardiovascular disease prevention.
Antimicrobial and Antifungal Applications
Clinical and in-vitro studies demonstrate that Polydatin exerts a strong antibacterial effect on pathogenic fungi, notably Trichophyton rubrum and Trichophyton interdigitum, which are primary causative agents of stubborn tinea and psoriasis. Additionally, compound formulations containing this extract have shown significant hepatoprotective (liver-protecting) effects.
Advanced Therapeutic Potential
Current research shows promising therapeutic effects for Polydatin in managing various chronic conditions, including tumors, diabetes, neurodegenerative diseases, and respiratory disorders. Its potent antioxidant pharmacological activity helps mitigate oxidative stress at the cellular level.
Applications in Cosmetics and Personal Care
Beyond nutraceuticals, Polydatin Powder is a highly valued active ingredient in the cosmetics and skincare industry. Its safety profile is excellent (risk factor rating of 1), generally recognized as safe for use, non-comedogenic, and suitable for pregnant women.
- Whitening and Freckle Removal: Polydatin effectively inhibits the activity of B-16 melanocytes, thereby reducing melanin synthesis. Simultaneously, it promotes macrophage activity, aiding in the clearance of cellular debris and pigment.
- Anti-Aging and Anti-Wrinkle: As a powerful antioxidant, it demonstrates a significant inhibitory effect on elastase, preserving skin elasticity and preventing structural degradation.
- Multifunctional Topical Use: Formulators can utilize this extract as a skin conditioning agent, antibacterial component, hair growth stimulant, and slimming agent in advanced cosmeceutical formulations.
Formulation Compatibility and Storage Recommendations
Due to its specific solubility profile, Polydatin Powder is ideally suited for oil-based or ethanol-based cosmetic formulations, emulsions, and encapsulated dietary supplements. Avoid formulating in purely aqueous systems or high-pH (alkaline) environments to prevent degradation and color shifting.
Storage: Store in a cool, dry place, away from direct sunlight and moisture. Keep containers tightly sealed to preserve the crystalline structure and bioactivity of the powder.
