Explore our premium range of highly standardized natural active ingredients manufactured in GMP-certified facilities for global export.
Ginkgo Biloba Extract EGb 761 is widely recognized as the preeminent standardized extract of Ginkgo biloba leaves, clinically demonstrated to alleviate symptoms of cognitive decline, age-related dementia, microcirculatory insufficiency, peripheral arterial occlusive disease (PAOD), and neurosensory disorders including tinnitus and vertigo. Sourced from botanical plantations governed under strict Good Agricultural and Collection Practices (GACP), this compound requires precise fractionation techniques to maintain its complex multi-constituent chemical profile while eliminating toxic native components like ginkgolic acids.
The therapeutic matrix of authentic EGb 761 is meticulously engineered. It is standardized to contain 22.0% to 27.0% Ginkgo Flavone Glycosides (primarily quercetin, kaempferol, and isorhamnetin) and 5.4% to 6.6% Terpene Lactones, composed of 2.8% to 3.4% Ginkgolides A, B, and C, and 2.6% to 3.2% Bilobalide.Crucially, the concentration of cytotoxic alkylphenols (ginkgolic acids) is strictly limited to less than 5 ppm (and optimized in our facility to <1 ppm) to prevent immunotoxic and allergenic reactions, satisfying both the European Pharmacopoeia (EP) and the United States Pharmacopeia (USP) monographs.

A comprehensive system of validation, keeping our botanical products strictly aligned with EP, USP, and CP pharmacopeias.
At UniCare, quality is not a retrofitted check; it is built into the process. We have established an industry-leading quality control framework. Using ultra-precise analytical instruments, we run exhaustive assays on every single batch of Ginkgo Biloba Extract EGb 761, validating fingerprint consistency, trace pesticide clearances, and heavy metal concentrations.
Our analytical capacity is driven by a CNAS certified central laboratory, deploying state-of-the-art testing equipment including: two UHPLC Agilent 1290 ultra-high performance liquid chromatographs, four HPLC Agilent 1260 systems, two HPLC Shimadzu LC-20AT systems, two HPLC Dionex UltiMate 3000 systems, two Shimadzu ELSD 2000ES detectors, one Shimadzu GC-2010 gas chromatograph, and one Shimadzu AA-7000 atomic absorption system. This array enables us to execute advanced diagnostic techniques including HPLC/UV quantification, GC head-space solvent evaluation, and ICP-MS micro-contamination screening.

Controlling quality from the seed: How our raw material cultivation bases and academic research partnerships secure superior active ingredient outputs.
We reinvest 10% of our annual net profit directly back into R&D. Beyond updating extraction steps, our dedicated team explores innovative bio-fermentation processes to bypass traditional constraints.
We work directly with growers to operate specialized Ginkgo biloba, Epimedium, Phellodendron, and Olive leaf plantations. These sites are run strictly according to Good Agricultural and Collection Practices (GACP) to guarantee chemical uniformity.
We partner closely with top research institutions, including the Beijing University of Chemical Technology, to develop and scale up innovative active ingredients from clinical pilot phases to industrial mass production.
By coordinating with seedling developers, we cultivate high-potency cultivars through traditional hybridization and genomic optimization. This research produces parent lines that yield up to 30% higher active flavone glycosides in their leaves compared to wild strains, helping us lower raw material costs and pass those savings directly on to our partners.
Addressing the critical logistical, regulatory, and localization concerns of international pharmaceutical and nutraceutical buyers.
Exporting active ingredients globally demands precise compliance. We provide complete documentation, including CEP, US DMF registration numbers, EU-REACH registration, and full stability testing dossiers. Our technical team works alongside your regulatory department to streamline product approvals, whether with the FDA, EFSA, or local health ministries.
China is home to over 70% of the world's Ginkgo biloba forests. Our extraction facility is strategically situated near major cultivation belts, guaranteeing a steady supply of fresh leaves. Combining this geography with our high-volume extraction capabilities, automated solvent recovery systems, and efficient supply networks, we offer stable pricing and prompt delivery even during market fluctuations.
The global dietary supplement industry is shifting rapidly toward clean-label, low-residue ingredients. Modern buyers demand zero-residue solvents and complete traceability. Our specialized acetone-water extraction process effectively isolates targeted therapeutic compounds while keeping alkylphenols below 1 ppm, perfectly aligning with these clean-label market expectations.
Standardized Ginkgo Biloba Extract EGb 761 is highly versatile and used across multiple product formulations:
Answering key technical, safety, and logistical questions from procurement managers and formulation chemists.
EGb 761 is a highly specific, clinically studied pharmaceutical-grade extract standardized to 24% flavone glycosides and 6% terpene lactones. It must follow a precise extraction protocol that keeps cytotoxic alkylphenols (ginkgolic acids) under 5 ppm (and below 1 ppm in our premium batches). Generic extracts often fail to meet these narrow standard ranges or display the required proportions of bilobalide and ginkgolides A, B, and C.
The acetone-water extraction process is uniquely effective at isolating the active terpene lactones and flavone glycosides while leaving behind unwanted fats, waxes, and toxic ginkgolic acids. The European Pharmacopoeia and USP monographs for standardized EGb 761 are based on this acetone extraction process. UniCare operates the only EU-GMP compliant acetone-water extraction line in China, ensuring authentic compliance.
Adulteration with free kaempferol, quercetin, or rutin is a common issue in lower-grade extracts to falsely boost HPLC test results. Our CNAS-certified laboratory checks the ratios of kaempferol to quercetin and isorhamnetin to quercetin. If these ratios fall outside the established natural botanical fingerprint, the batch is rejected. We also use TLC comparison and DNA barcoding to confirm raw leaf authenticity.
We provide comprehensive regulatory documentation to support international registration, including DMF (Drug Master File) filings, CEP (Certificate of Suitability), EU-GMP certificates, stability testing reports (conducted under ICH guidelines), allergen statements, GMO-free certifications, and Kosher/Halal approvals.
When stored in its original double-layered polyethylene bags inside airtight fiber drums, stored in a cool, dry place away from direct sunlight, our Ginkgo Extract EGb 761 has a validated shelf life of 36 months. We perform ongoing stability testing under controlled temperature and humidity conditions to verify long-term assay stability.
Yes, we can customize particle sizes (mesh size) and bulk density to match your manufacturing process, whether for direct-compression tablets or capsule filling. We can also modify the carrier options or active concentration profiles to meet your specific formulation requirements.
