Introduction of Polygonum Cuspidatum Extract

Polygonum Cuspidatum Extract Resveratrol is a high-value natural plant extract derived from the dried rhizomes of Polygonum cuspidatum (Polygonaceae family). It is widely used in health care, cosmetics, food supplements and pharmaceutical intermediates for its high purity, stable activity and diverse biological functions.

Raw Material Source

Raw materials are sourced from pollution-free planting bases in China. We select mature, disease-free rhizomes, process them at low temperature to retain active ingredients, and conduct strict detection to ensure compliance with international standards.

Extraction Process

Adopting advanced low-temperature ultrasonic-assisted extraction and column chromatography purification, we use food-grade ethanol as solvent. The whole process is carried out in a GMP-certified workshop to ensure product stability and active ingredient integrity.

Active Ingredient Content

The core active ingredient is trans-resveratrol (CAS: 501-36-0), with customizable specifications (50%, 70%, 90%, 98%, detected by HPLC). It also retains polydatin, emodin and other accompanying ingredients with synergistic effects.

Differentiation Advantages

Our product has four core advantages: traceable raw materials, advanced low-temperature extraction (92%+ active ingredient conversion rate), high purity (up to 98%, low solvent residue) and multi-component synergy.

Key Active Compounds

The main active components are stilbenes and anthraquinones, with clear pharmacological effects:

• Resveratrol (CAS: 501-36-0): White to light yellow powder, slightly soluble in water, easily soluble in organic solvents, with strong antioxidant, anti-inflammatory and cardioprotective activities.

• Polydatin (CAS: 65914-17-2): Glycoside form of resveratrol, convertible in human body, with anti-inflammatory, hepatoprotective effects and enhanced bioavailability.

• Emodin (CAS: 518-82-1): Anthraquinone compound with antibacterial, anti-inflammatory and liver-protecting effects, regulating intestinal function.

Benefits

Based on extensive research, the extract exerts multiple beneficial effects through regulating key signaling pathways:

Powerful Antioxidant Capacity

Scavenges free radicals, reduces oxidative damage, activates antioxidant signaling pathways, and is superior to common antioxidants like vitamin C and E.

Anti-Inflammatory and Analgesic Effects

Inhibits pro-inflammatory cytokines, relieves chronic inflammation and mild pain, serving as a safe natural anti-inflammatory raw material.

Cardiovascular Protection

Protects vascular endothelial cells, supports vascular health, supports lipid balance and pressure, and supports vascular wellness.

Skin Health Improvement

Inhibits tyrosinase, lightens spots, repairs skin barriers, delays aging, and is a core raw material for skin wellness support and whitening cosmetics.

Metabolic Regulation and Liver Protection

Improves insulin sensitivity, reduces blood glucose and lipid, and protects liver cells from toxins and alcohol damage.

Neuroprotective Effect

Penetrates the blood-brain barrier, protects nerve cells, and may help with neurodegenerative diseases and cognitive function.
