Premium Peanut Skin Extract 95% Proanthocyanidins - Leading China Suppliers & Factory for Antioxidant Solutions
Bioactive Composition
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 active compounds in Peanut Skin Extract?
Peanut Skin Extract is highly rich in Proanthocyanidins (OPCs), which make up 60–95% of its composition, alongside essential polyphenols, flavonoids (such as catechins and epicatechins), Vitamin E, zinc, and magnesium.
How does Peanut Skin Extract support renal health?
It offers kidney protection by mitigating kidney injury—reducing serum creatinine, urea nitrogen, and uric acid levels. It also exhibits antifibrotic effects by suppressing collagen deposition and fibrotic pathways in renal tissues.
What dermatological benefits does Peanut Skin Extract provide?
It provides anti-aging benefits by preserving collagen and reducing wrinkles, aids in acne management by reducing sebum overproduction, and helps correct hyperpigmentation to improve skin tone uniformity.
In what industries is Peanut Skin Extract utilized?
It is widely used in the food industry as a natural antioxidant and colorant, in the health supplement sector for vascular and antioxidant support, and in biomedical research for diabetes management and neuroprotection.
What is the botanical source and extraction solvent for this product?
The extract is derived from the skin of Arachis hypogaea (peanut) and is processed using Ethanol/Water as the extraction solvent.
