Explore our premium raw material extracts sourced and processed under strict GMP regulations to support global wellness brands.
Ginkgo Biloba Extract (GBE) is one of the most widely commercialized botanical raw materials in the global pharmaceutical, health supplement, and functional food sectors. Historically valued in traditional Eastern systems, modern clinical science has verified the therapeutic efficacy of Ginkgo’s unique chemical composition, particularly its flavone glycosides and terpene lactones. As the global population ages and the demand for cognitive-enhancing supplements ("nootropics") and cardiovascular regulators spikes, Ginkgo Biloba has transitionally evolved from a traditional herbal remedy to a major ingredient in evidence-based medicine.
In international markets, Ginkgo Biloba Extract is standardized according to official pharmacopoeias (USP, EP, and ChP). Commercial buyers evaluate suppliers not only on cost but on their capability to control trace contaminants, particularly ginkgolic acids, which are known to cause cytotoxic, mutagenic, and allergenic reactions. Consequently, the manufacturing landscape is highly concentrated among manufacturers who command advanced separation, filtration, and purification technologies.
Meeting USP, EP, and ChP standards is non-negotiable. Standard parameters mandate Flavone Glycosides ≥ 24.0% and Terpene Lactones ≥ 6.0%, with Ginkgolic Acids strictly kept below 5 ppm (or 1 ppm for premium applications).
Unveiling the precise chromatographic separation and optimization techniques utilized in our state-of-the-art facilities.
Raw dry leaves of Ginkgo biloba are crushed and subjected to multi-stage countercurrent extraction using food-grade ethanol and purified water. Temperature controls (60°C–70°C) prevent the thermal degradation of delicate bioflavonoids.
The crude liquid passes through specifically tailored macroporous adsorption columns. This essential step selectively isolates flavone glycosides (Quercetin, Kaempferol, Isorhamnetin) and terpene lactones (Ginkgolides A, B, C, and Bilobalide) while washing away unwanted sugars and plant pigments.
Because ginkgolic acids are highly allergenic, we run patented liquid-liquid extraction and purification phases. This successfully reduces the ginkgolic acid content to less than 1 ppm, ensuring a highly biocompatible and safe profile for functional supplements.

Nanjing Tong Rui Bio-Tech Co., Ltd. (TRB) has established itself as a leading China manufacturer and exporter of herbal extracts and their derivatives for more than 20 years. TRB is a technology-based enterprise that seamlessly combines scientific research and development, smart manufacturing, and international market sales.
We pride ourselves on our rapid growth and dedicated service within the plant extraction industry. As a testament to our excellence, we were honored with the 2026 "Global Biotechnology and Life Sciences Award" - "Best Global Herbal Extract Provider 2026". We offer a comprehensive product catalog that spans Herbal Extracts, Sweeteners, Nootropics, Vegetable & Fruit Juice Powder, Essential Oils, and Bee Products.
TRB currently operates three distinct factories: one dedicated entirely to herbal extract processing, one for bee products, and another for animal-derived products. These state-of-the-art facilities possess certificates such as GMP, ISO, HACCP, ORGANIC, FDA, HALAL, and KOSHER, allowing us to supply over 60 countries worldwide with trusted, highly certified raw ingredients.
Our raw Ginkgo Biloba leaves are harvested from geographically verified GAP (Good Agricultural Practices) plantations in China. Cultivation under precise conditions controls soil minerals and pesticides, guaranteeing high-grade starting material.
Operating localized botanical refineries in China yields dramatic economic benefits. Raw materials, steam energy, chemical solvents, and high-performance labor are optimized through automated DCS systems to minimize batch variability and cost.
China is home to over 70% of the world's Ginkgo Biloba botanical resources. This geographic and biological dominance forms the foundation of our supply chain resilience. As a premier manufacturer, TRB leverages this localization to secure steady, year-round access to premium leaves, bypassing the geopolitical and climatic vulnerabilities that impact international raw material providers.
By establishing long-term, direct purchase agreements with local farming cooperatives, we eliminate intermediate trading layers. This guarantees trace-monitored supply from cultivation, leaf drying, storage, and processing, culminating in industrial reliability. Even during times of global transport delays or raw-crop volatility, TRB maintains buffer stocks and operational continuity, providing global buyers with predictable costs and uninterrupted container shipments.
How international pharmaceutical and nutraceutical brands integrate standardized Ginkgo Biloba Extract into consumer-ready products.
Ginkgo Biloba is a fundamental element in cognitive-support formulations. By encouraging cerebral blood circulation and protecting neurons from oxidative stress, it is commonly blended with Alpha-GPC, Phosphatidylserine (PS), and Huperzine-A to target mental clarity, memory retention, and long-term focus.
Active flavones inhibit platelet-activating factor (PAF) and relax vascular walls, promoting blood flow to extremities. Applied in clinical health supplements designed to support patients experiencing peripheral artery disease (PAD), cold extremities, and inner-ear vertigo.
High concentration of antioxidant compounds (quercetin, kaempferol) scavenges free radicals, protecting skin collagen structure from UV-induced aging. Ginkgo extracts are integrated into premium serums, anti-wrinkle creams, and oral skin-whitening formulas.
Global distribution of botanical extracts demands complete transparency and compliance. At TRB, every batch of Ginkgo Biloba Extract is accompanied by a comprehensive package of analytical documentation. We use advanced high-performance liquid chromatography (HPLC) coupled with mass spectrometry to ensure the correct chemical fingerprint of the active ingredients, excluding synthetic adulteration (such as spiked routine/free quercetin).
Our quality management systems are certified under international protocols. We regularly update our DMF (Drug Master Files) and offer full support for regional regulatory submissions, including the US FDA, EFSA, and local authorities. Our active components are verified organic, non-GMO, allergen-free, and comply strictly with heavy metal, pesticide residue, and microbiological standards required by demanding Western buyers.
Our laboratory utilizes High-Performance Liquid Chromatography (HPLC) to identify and quantify the distinct peak profiles of Quercetin, Kaempferol, and Isorhamnetin. We check the peak ratios to verify that no synthetic bioflavonoids have been added to standard batches.
Each production run undergoes Inductively Coupled Plasma Mass Spectrometry (ICP-MS) to confirm heavy metal concentration is well below international regulatory thresholds. Additional screenings check for over 300 pesticide residues, plasticizers, and residual solvents.
TRB is heavily investing in research and development to pioneer the next generation of brain-health and longevity compounds.
In recent years, TRB has focused on the research and development of Nootropics products, such as Brain Health Herb Extract, Anti-Aging Herb Extract, and Longevity Herb Extract. By integrating traditional Ginkgo chemistry with modern delivery systems (like liposomal encapsulation and nano-emulsions), we aim to optimize oral bioavailability and crossing of the blood-brain barrier. Our research efforts are directed toward clinical-grade, highly pure fractions of Bilobalide and Ginkgolide B for target therapeutics in neurodegenerative contexts.
Developing liposome-bound Ginkgo molecules to maximize cell absorption and enhance overall bioavailability in functional liquids and softgels.
Refining extraction to isolate high-purity single active molecules like pure Ginkgolide B to serve clinical trials in stroke recovery and neuroprotection.
Moving toward enzyme-assisted extraction and green water-based processes to minimize organic solvent waste and align with global zero-carbon goals.
