This extract features high water solubility and moderate alcohol compatibility, making it ideal for aqueous phases in emulsions, beverages, and complex formulation systems.

Our product is adaptable and safe, making it suitable for many sectors. It is a natural ingredient in antioxidant and anti-aging health products, functional drinks, and beauty nutraceuticals. Capsules, pills, solid liquids, compressed candies, and meal replacements incorporate the extract well.
Serums, toners, and skincare products for sensitive skin contain it as a natural botanical addition. Its antibacterial qualities against common skin diseases allow formulators to create preservative-free or self-preserving cosmetics.
Natural functional additives are used in drinks, dairy products, baked goods, jams, and confectionary to color and taste and boost functionality.

Purple Willow Extract neutralizes free radicals that promote cellular aging and tissue damage, providing significant antioxidant defense. Formulations that handle oxidative stress benefit from it.
Supporting cellular regeneration and skin suppleness gives it anti-aging benefits. It fights aging in beauty products and functional drinks.
You may design numerous product forms without reformulation due to its high safety profile and outstanding compatibility with various distribution modes. Active compounds are preserved in acidic to neutral environments because the extract is stable at pH 3.5–6.5.
The standard specification ensures component content and batch uniformity, decreasing production process and product performance variability.
Shaanxi Zhenhuacui Biotechnology incorporates innovative extraction technologies, such as supercritical CO₂ systems and fermentation engineering, with over a decade of manufacturing expertise We spend 60% of our staff to R&D, assuring creativity and technical assistance for your formulation issues.
OEM/ODM services for gummies, pills, powders, and capsules with minimal MOQs are available for organizations of any size. Standard extracts ship in 10 days, while customized items take 20. The accelerated green channel delivers in 7–10 days for urgent needs.
Our DHL, FedEx, and SF Express logistics network delivers securely and quickly globally. Supply chain transparency and regulatory compliance are assured by cGMP, FSSC22000, ISO9001, HACCP, HALAL, KOSHER, and Organic certifications.

cGMP, FSSC22000, ISO9001, HACCP, HALAL, KOSHER, and Organic certification for sustainably sourced materials are among our manufacturing facility's international certifications. These qualifications show our dedication to high manufacturing and safety standards across all product categories.

Complete quality control is implemented from raw material sourcing to product delivery. Salicin and Flavonoid content are measured by HPLC in each batch to ensure specification compliance. Standard QC techniques include microbiological testing, heavy metal screening, pesticide residue analysis, and stability tests. Our quality assurance team monitors important control points during extraction, purification, and packing to ensure product quality and traceability.
Certificate of Analysis documentation accompanies every batch, detailing active ingredient percentages, physical characteristics (appearance, particle size, solubility), microbiological test results, heavy metal content, pesticide residues, and moisture levels. COA reports provide regulatory and quality transparency with batch number, manufacturing date, expiration date, and QC approval signatures.
