Product Description

Sophora Japonica Flower Bud Extract is derived from the dried unopened flower buds of Sophora japonica L. (commonly known as Huai Mi). The extract is prepared using ethanol reflux extraction, followed by macroporous resin purification and low-temperature spray drying. The production strictly follows GMP standards. By controlling extraction temperature (55–60°C) and elution rate during purification, the Rutin retention rate is ≥90%, avoiding degradation caused by high temperatures.

Key Active Components

Rutin (Vitamin P): Enhances vascular elasticity and reduces vascular permeability; core active ingredient in cardiovascular health. Exhibits strong antioxidant activity, with free radical scavenging ability 1.5 times that of Vitamin C.

Quercetin: Hydrolysis product of Rutin, with superior anti-inflammatory and antibacterial properties. Can inhibit histamine release and alleviate skin allergic reactions.

Isorhamnetin: Supports and enhances Rutin's antioxidant effects, synergistically protects vascular endothelial cells, and reduces lipid deposition.

Product Advantages

High and Stable Active Content

Standard grade contains ≥80% Rutin; high-purity grade can exceed 98%. Batch-to-batch variation <3%, meeting pharmaceutical-grade requirements.

Low-temperature spray drying (inlet temperature 180°C, outlet 80°C) preserves Rutin activity with retention rate >95%, avoiding thermal decomposition.

Applications

Pharmaceutical & Healthcare

Cardiovascular Drugs: Rutin tablets, compound Rutin tablets for hypertension, arteriosclerosis, and capillary bleeding (e.g., gum bleeding, nosebleeds). Clinical efficacy >85%.

Hemostatic Agents: Topical hemostatic powders and sponges for trauma and surgical bleeding; reduces prothrombin time by 20%.

Anti-inflammatory Drugs: Capsules for rheumatoid arthritis to relieve joint swelling and pain; ophthalmic drops for conjunctivitis and keratitis with soothing anti-inflammatory effect.

Cosmetics & Personal Care

Skincare Products: Antioxidant serums (delay skin aging), sensitive skin repair lotions (soothe redness), eye care products (reduce under-eye redness). Effective at 0.5–2% concentration.

Sunscreen Products: Synergizes with UV filters (e.g., Octocrylene), enhances sun protection and reduces UV-induced free radical damage.

Oral Care: Mouthwash and toothpaste to inhibit gum bleeding, prevent gingivitis, and improve capillary stability in gums.

Food & Nutraceuticals

Functional Foods: Added to solid beverages and pressed candies as a cardiovascular health and antioxidant supplement. Recommended daily intake: 50–100 mg.

Natural Food Additive: Used in juices, jams, and baked goods for antioxidant effect (extends shelf life by 30%) and coloring (light yellow to yellow), compliant with GB 2760 "National Food Safety Standard – Food Additive Usage Standards."

Health Supplements: Capsules and softgels to help regulate blood lipids (lower triglycerides), suitable for middle-aged, elderly, and high-cholesterol populations.

Other Applications

Feed Additive: For livestock and poultry feed to enhance immunity, reduce stress (e.g., transport stress mortality), and improve survival rate.

Natural Dye: Textile dyeing to achieve light yellow to yellow-brown shades, meeting eco-friendly printing and dyeing standards; suitable for baby clothes and home textiles.

Technical Support & Customization

Specification Customization: Full range of Rutin products 10–98%, with desalting and decolorization options to meet cosmetic transparent formula requirements. Water-soluble Rutin available via β-cyclodextrin inclusion.

Formulation Development: Customized solutions for pharmaceutical intermediates, cosmetic anti-sensitivity formulas (e.g., Rutin + Panthenol), and antioxidant systems for food products, including stability test reports.
