Product Overview
Ginkgo Biloba Leaf Extract is one of the most extensively studied and commercially significant botanical extracts in the global nutraceutical and pharmaceutical industries. Derived from the dried leaves of Ginkgo biloba L. — one of the world's oldest living tree species — this standardized extract is produced in accordance with internationally recognized quality benchmarks and is commonly referenced under the designation EGB 761.
Extract Makers supplies pharmaceutical-grade Ginkgo Biloba Leaf Extract in bulk quantities, formulated to the industry-standard specification of 24% Flavone Glycosides and 6% Terpene Lactones. This precise standardization ensures consistent bioactive potency across every production batch, making it a reliable choice for manufacturers, formulators, importers, and private label brands worldwide.
Active Constituents and Chemical Profile
The therapeutic and functional value of Ginkgo Biloba Leaf Extract is attributed to two primary classes of bioactive compounds:
Flavone Glycosides (24%)
The flavone glycoside fraction is composed predominantly of quercetin, kaempferol, and isorhamnetin — flavonoid glycosides with well-documented antioxidant activity. These compounds are responsible for the extract's free radical scavenging capacity and play a central role in its anti-aging and cytoprotective properties.
Terpene Lactones (6%)
The terpene lactone fraction includes:
- Ginkgolides A, B, and C — comprising approximately 2.8% to 3.4% of the extract
- Bilobalide — comprising approximately 2.6% to 3.2% of the extract
Ginkgolides, particularly Ginkgolide B, are recognized for their role in supporting circulatory function and platelet-activating factor (PAF) inhibition. Bilobalide has attracted scientific interest for its potential neuroprotective properties. Together, these terpene lactones contribute significantly to the extract's bioactivity profile.

Botanical Source and Raw Material Origin
Ginkgo Biloba Leaf Extract is sourced from cultivated Ginkgo biloba plantations, with China being the world's primary commercial production region — particularly the provinces of Jiangsu, Shandong, and Guangxi. Leaves are harvested at peak maturity to ensure maximum flavonoid and terpene lactone content, then subjected to rigorous sorting, cleaning, and drying protocols prior to extraction.
Raw material traceability is maintained throughout the supply chain, from cultivation and harvest through to finished extract production, supporting full-batch documentation and transparent quality assurance.
Extraction and Manufacturing Process
The production of standardized Ginkgo Biloba Leaf Extract involves a multi-step extraction and purification process:
- Raw material preparation — Dried ginkgo leaves are milled and pre-processed to optimize extraction efficiency.
- Solvent extraction — Bioactive compounds are extracted using food-grade or pharmaceutical-grade solvents under controlled temperature and pressure conditions.
- Filtration and concentration — The crude extract is filtered, concentrated, and subjected to further purification to remove undesirable compounds, including ginkgolic acids (known allergens), which are carefully controlled to meet acceptable limits.
- Standardization and blending — The extract is analytically tested and blended to achieve the target specification of 24% flavone glycosides and 6% terpene lactones.
- Spray drying or vacuum drying — The final product is converted to a free-flowing powder with consistent particle size and low moisture content.
- Quality control and release testing — Every batch undergoes comprehensive in-process and finished-product testing before release.
All manufacturing operations are conducted in GMP-certified facilities, ensuring compliance with international production standards and regulatory requirements.
