China Peanut Skin Extract Proanthocyanidin 95% - Top Suppliers & Factory for Antioxidant Benefits
🌿 Bioactive Composition
Key Phytochemical Profile
- 1, Proanthocyanidins (OPCs): Constitute 60–95% of Peanut Skin Extract, acting as powerful antioxidants that neutralize free radicals and reduce oxidative stress.
- 2, Polyphenols & Flavonoids: Including catechins and epicatechins, which enhance anti-inflammatory and antimicrobial effects.
- 3, Vitamins & Minerals: Vitamin E (tocopherols), zinc, and magnesium contribute to skin barrier repair and UV protection.
⚙️ Mechanisms of Action
1. Antioxidant Activity
- A: Free Radical Scavenging: OPCs donate electrons to unstable free radicals (e.g., ROS), preventing cellular DNA and lipid damage.
- B: Enzyme Modulation: Suppresses xanthine oxidase (XOD) activity, reducing uric acid production and mitigating gout or kidney injury.
2. Anti-Inflammatory Pathways
- A: Cytokine Inhibition: Downregulates pro-inflammatory markers (IL-1β, TNF-α) and inhibits NLRP3 inflammasome activation, curbing chronic inflammation.
- B: Endoplasmic Reticulum Stress (ERS) Regulation: Alleviates ERS-induced apoptosis in renal cells, protecting against metabolic stress.
❤️ Health Benefits
1. Renal Protection
- A: Kidney Injury Mitigation: In rat studies, PSE (200 mg/kg/day) reduced serum creatinine, urea nitrogen, and uric acid by 30–40% in high-fat-diet models, preventing renal tubular degeneration.
- B: Antifibrotic Effects: Suppresses collagen deposition and fibrotic pathways in renal tissues.
2. Metabolic Health
- A: Lipid Regulation: Lowers LDL oxidation and triglycerides, reducing risks of atherosclerosis.
- B: Hyperglycemia Control: Enhances insulin sensitivity and glucose uptake in adipose tissues.
3. Dermatological Benefits
- A: Anti-Aging: Vitamin E and OPCs inhibit MMP enzymes, preserving collagen and reducing wrinkles.
- B: Acne Management: Zinc and magnesium reduce P. acnes proliferation and sebum overproduction.
- C: Hyperpigmentation Correction: Vitamin C blocks tyrosinase activity, lightening dark spots and improving skin tone uniformity.

Frequently Asked Questions
❓
What are the primary bioactive components in Peanut Skin Extract?
Peanut Skin Extract is highly concentrated with Proanthocyanidins (OPCs), which make up 60–95% of the extract. It also contains active polyphenols, flavonoids (such as catechins and epicatechins), and essential vitamins and minerals like Vitamin E, zinc, and magnesium.
❓
How does Peanut Skin Extract support kidney health?
It provides renal protection by mitigating kidney injury and reducing serum creatinine, urea nitrogen, and uric acid levels. Furthermore, it exerts antifibrotic effects by suppressing collagen deposition and fibrotic pathways in renal tissues.
❓
What are the dermatological benefits of using this extract?
Peanut Skin Extract offers anti-aging benefits by preserving collagen and reducing wrinkles, aids in acne management by regulating sebum production, and helps correct hyperpigmentation by blocking tyrosinase activity to lighten dark spots.
❓
What are the main applications of Peanut Skin Extract in the food and supplement industries?
In the food industry, it serves as a natural antioxidant and red pigment colorant. In the supplement industry, it is widely formulated into capsules, softgels, tablets, and functional beverages to support vascular health, blood circulation, and antioxidant defenses.
❓
What is the botanical origin and extraction solvent used for this product?
The extract is derived from the skin of Arachis hypogaea (commonly known as peanut) and is processed using a safe and efficient solvent mixture of Ethanol and Water.
