Active Flavonoid Composition & Functional Roles
Sophora Japonica Extract is characterized by a rich profile of bioactive flavonoids. Each compound contributes distinct functional and formulation value:
Quercetin
A potent antioxidant flavonol widely studied for its anti-inflammatory, anti-allergic, and immune-support properties. Commonly used in high-end nutraceutical formulations.
Rutin (Vitamin P)
A glycoside of quercetin known for strengthening capillary walls, improving circulation, and reducing vascular permeability. Frequently used in cardiovascular support products.
Troxerutin
A semi-synthetic derivative of rutin with enhanced bioavailability, widely applied in pharmaceutical-grade vascular protection formulations.
Total Flavonoids
Provide broad-spectrum antioxidant activity, supporting oxidative stress reduction and overall cellular protection.
We support targeted standardization depending on your formulation objective.
Extraction & Standardization Process
Our Sophora Japonica Extract is produced under controlled conditions to ensure consistency, purity, and bioactivity:
Raw Material Selection
Carefully selected Sophora japonica buds/flowers with verified botanical identity
Gentle Extraction
Water or ethanol-based extraction to preserve heat-sensitive flavonoids
Purification & Concentration
Removal of impurities while concentrating active compounds
Standardization (HPLC Verified)
Precise adjustment of Quercetin / Rutin / Troxerutin content
Drying & Milling
Spray drying or low-temperature processing for optimal stability
Ensures batch-to-batch consistency for industrial applications
Stability & Formulation Considerations
To maximize product performance in finished formulations:
Light Sensitivity
Flavonoids such as quercetin are sensitive to UV exposure
→ Use opaque or UV-resistant packaging
pH Stability
Best stability in neutral to slightly acidic conditions (pH 5–7)
Solubility Enhancement
Standard extracts have limited water solubility
→ Liposomal or modified forms recommended for beverages
Thermal Stability
Avoid prolonged high-temperature processing (>80°C)
We offer customized solutions for improved solubility and bioavailability
