Product Advantages

Exceptional Purity: Minimum 98% dihydromyricetin content ensures maximum potency and allows for lower inclusion rates while maintaining efficacy.

Superior Bioactivity: High-purity form preserves the natural flavonoid structure, ensuring optimal bioavailability and biological activity.

Rigorous Quality Control: Every batch is tested for heavy metals, residual solvents, and microbial contaminants to meet the highest safety standards for global markets.

Multi-Functional Applications: The unique properties of dihydromyricetin support diverse formulation needs across nutraceutical, functional food, and cosmeceutical sectors.

Comprehensive Documentation: Full regulatory support, including specification sheets, stability data, and technical dossiers for product registration.

Technical & Process Highlights

Our manufacturing process is designed to maximize purity while preserving the integrity of this delicate flavonoid.

Controlled Extraction: Fresh Ampelopsis grossedentata leaves are extracted using a water-ethanol gradient system optimized to isolate dihydromyricetin while minimizing co-extracted impurities selectively.

Multi-Stage Purification: The crude extract undergoes sequential purification steps, including macroporous resin chromatography, crystallization, and recrystallization to achieve ≥ 98% purity.

Low-Temperature Processing: Critical steps are performed under controlled temperature conditions to prevent thermal degradation of the heat-sensitive flavonoid structure.

Crystallization Control: Our proprietary crystallization process yields uniform, free-flowing crystals with consistent particle size, enhancing handling and blending characteristics.

Stability Optimization: The final product is dried under reduced pressure to minimize residual moisture, which significantly improves shelf stability and prevents degradation.

Full Traceability: From plantation harvest to final packaging, every step is documented and traceable for complete supply chain transparency.
