Product Description

Introduction

Pterostilbene, a natural dimethoxylated stilbenoid, is mainly extracted from Pterocarpus marsupium heartwood and Vaccinium spp. fruits. Produced via eco-friendly supercritical ethanol extraction, simulated moving bed chromatography purification and recrystallization, its Pterostilbene content is strictly controlled at 98% (HPLC), complying with international pharmaceutical, dietary supplement and cosmetic standards.

Differentiated advantages: Compared with resveratrol, it has higher bioavailability due to its methylated structure, stronger antifungal activity (5x that of resveratrol) and better blood-brain barrier penetration. We use pollution-free raw materials and green extraction technology with low energy consumption and no harmful residues.

Key Active Compounds

The core active compound is Pterostilbene (CAS: 537-42-8), also called trans-3,5-dimethoxy-4-hydroxystilbene (C₁₆H₁₆O₃, molecular weight 256.30). As a resveratrol analog, it has stronger activity and stability due to two methoxy groups. With ≥98% purity (HPLC) and no impurities, it ensures application stability and effectiveness.

Benefits

  • Antioxidant Activity: Scavenges free radicals, inhibits lipid peroxidation, delays aging, with comparable antioxidant capacity to resveratrol but better bioavailability.

  • Metabolic Regulation: Activates PPARα, regulates glucose and lipid metabolism, helps supports healthy levels and lipid levels.

  • Anti-inflammatory & Antifungal: Inhibits inflammatory factors, relieves inflammation, and has strong antifungal activity for treating fungal infections.

  • Cardiovascular Protection: Improves vascular endothelial function, inhibits platelet aggregation, supports vascular wellness.

Application Cases

  • Dietary Supplement Field: Added to capsules, tablets and powders for antioxidant, skin wellness support and metabolic regulation; exported to over 60 countries.

  • Cosmetics Field: Used in skin wellness support, whitening and repairing products for its antioxidant and anti-inflammatory properties.
