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

Production Flow Chart
Frequently Asked Questions
What are the primary active components in Peanut Skin Extract?
Peanut Skin Extract is highly concentrated with Oligomeric Proanthocyanidins (OPCs), which make up 60–95% of the extract. It also contains active polyphenols, flavonoids (like catechins and epicatechins), and essential vitamins and minerals such as Vitamin E, zinc, and magnesium.
How does Peanut Skin Extract benefit kidney health?
Studies indicate that Peanut Skin Extract helps mitigate kidney injury by reducing serum creatinine, urea nitrogen, and uric acid levels. It also helps suppress collagen deposition and fibrotic pathways in renal tissues, offering significant antifibrotic protection.
Can Peanut Skin Extract improve skin health and appearance?
Yes. Its high concentration of Vitamin E and OPCs acts against aging by inhibiting collagen-degrading enzymes. Additionally, zinc and magnesium help regulate sebum to manage acne, while its components block tyrosinase activity to correct hyperpigmentation and even out skin tone.
What are the main applications of Peanut Skin Extract in the food industry?
In the food sector, Peanut Skin Extract is utilized as a natural antioxidant to preserve meats and fats, a natural red pigment colorant, and a functional ingredient in various health beverages and dietary supplements.
What solvents are used to produce Peanut Skin Extract?
The extract is obtained from the skin of Arachis hypogaea (peanut) using a safe and standard extraction process with Ethanol and Water as solvents.
