Oleuropein powder is a premium, non-toxic furanocoumarin glycoside compound renowned for its rich profile of natural antioxidants. Combining the synergistic benefits of flavonoids, polyphenols, and furanocoumarins, this highly sought-after botanical extract serves as a cornerstone ingredient for manufacturers in the dietary supplement, functional food, and personal care industries. Extracts China provides scientifically backed, high-concentration oleuropein powder designed to meet the stringent demands of global B2B procurement.
Botanical Source & Advanced Production Technology
The efficacy of oleuropein powder is deeply rooted in its sourcing and extraction methodology. Extracts China adheres to a rigorously controlled supply chain to ensure maximum active constituent retention.
Sustainable Sourcing & Harvesting
To guarantee peak phytochemical potency, healthy 1-2 year old olive leaves are manually harvested during the optimal botanical accumulation periods of May and June. Post-harvest, the leaves undergo low-temperature blanching and vacuum drying within a critical 4-hour window. This rapid processing protocol maximizes the preservation of heat-sensitive active substances, notably oleuropein and hydroxytyrosol, while effectively preventing oxidative degradation.
Patented Extraction & Purification Process
Our manufacturing facility employs a patented low-temperature ethanol and water two-phase extraction, synergized with ultrasonic-assisted cell disruption. This advanced methodology increases the extraction rate by 50% and reduces processing time to just 1 hour. Consequently, the hydroxytyrosol conversion rate achieves ≥95%, significantly outperforming traditional extraction techniques.
The enrichment phase utilizes macroporous resin (HPD-300) with an adsorption rate exceeding 90%. This is followed by 5kDa ultrafiltration for precise impurity removal and nanofiltration concentration at temperatures ≤40℃. The result is an exceptionally pure oleuropein powder reaching up to 80% purity by HPLC, with an impurity removal rate (including polysaccharides and waxes) exceeding 98%.

Quality Control & Certifications (EEAT)
Extracts China operates a state-of-the-art manufacturing facility equipped with a Class 10,000 cleanroom testing center. Our quality management systems are certified by ISO 9001, ISO 22000, FSSC 22000, and cGMP. Furthermore, we possess CNAS-accredited testing capabilities, ensuring all test results are internationally recognized and compliant with global regulatory standards.
Comprehensive Precision Testing
- Quantitative Analysis of Active Ingredients: High-performance liquid chromatography (HPLC) is utilized to accurately quantify oleuropein (10%-80%) and hydroxytyrosol (2%-10%) content, maintaining an RSD of <3% to guarantee active ingredient compliance.
- Safety Screening: GC-MS and ICP-MS technologies are deployed to detect heavy metals (Pb/As/Cd < 10ppm), pesticide residues, and solvent residues in strict accordance with EU REACH standards. Microbial parameters (total bacterial count, mold, Salmonella) fully comply with EP/USP standards.
Innovative Microencapsulation Stabilization Technology
Hydroxytyrosol is highly susceptible to oxidation and moisture absorption. To resolve this formulation challenge, Extracts China utilizes advanced microencapsulation stabilization technology. By employing a sodium alginate-chitosan composite encapsulation matrix, we significantly enhance the ingredient's stability. The finalized product boasts a 24-month shelf life at room temperature and is available in both water-soluble and alcohol-soluble formulations, ensuring seamless integration into health supplements, functional foods, and cosmetics.
Core Functions & Health Benefits
1. Potent Antioxidant Activity
Oleuropein powder exhibits powerful antioxidant properties by neutralizing free radicals and mitigating oxidative stress, thereby protecting cellular structures from damage. This mechanism plays a crucial role in intervening in pathological processes associated with aging, cardiovascular disease, and diabetes.
2. Anti-inflammatory Support
Oleuropein effectively suppresses the production of pro-inflammatory factors, alleviating inflammatory responses. This offers promising adjunctive therapeutic benefits for chronic inflammatory conditions, including arthritis and inflammatory bowel disease.
3. Natural Antimicrobial Properties
Possessing inherent antimicrobial characteristics, oleuropein inhibits the proliferation of specific bacteria, viruses, and fungi, demonstrating significant potential in the prevention and management of infections.
Industry Applications
