Product Overview


Botanical Source & Physical Traits

Ginkgo Biloba Leaf Extract is derived from the dried leaves of Ginkgo biloba L.—a ancient tree (often called the “living fossil”) with a 2,000-year history in Traditional Chinese Medicine (TCM). Our extract is a fine light brownish yellow to brown powder with a characteristic bitter taste, soluble in ethanol and water solutions for easy formulation.


Key Active Components

The extract’s efficacy relies on three primary compound groups, quantified via HPLC:

Total Flavone Glycosides: ≥24% (supports antioxidant and cardiovascular benefits).

Total Ginkgolides (Lactones): ≥6% (drives neuroprotective effects).

Ginkgolic Acid: ≤5ppm (strictly controlled to avoid side effects; our latest batch tested at 1.43ppm).

Additional components include quercetin, kaempferol, and isorhamnetin—flavonoids that enhance the extract’s overall activity.

Product Benefits


Alzheimer’s & Dementia Prevention

Ginkgo Biloba Extract improves blood flow to the brain and protects neurons from oxidative damage, reducing the risk of age-related dementia and Alzheimer’s disease. It may also alleviate mild cognitive symptoms (e.g., forgetfulness) in older adults.


Memory & Focus Improvement

By increasing cerebral circulation and enhancing neurotransmitter activity, the extract boosts memory retention, attention span, and mental clarity. It is popular among students and professionals seeking natural cognitive support.


Cardiovascular Health Support

It relaxes blood vessels, improves peripheral circulation, and reduces blood pressure—making it useful for managing peripheral vascular disease (e.g., cold hands/feet) and supporting heart health. It also inhibits platelet aggregation, lowering the risk of blood clots.


Antioxidant & Anti-Aging Effects

Total flavone glycosides neutralize free radicals, slowing cellular aging and reducing damage to skin, organs, and tissues. Regular use may improve skin elasticity, reduce wrinkles, and support overall longevity.


Antibacterial Activity

The extract inhibits the growth of harmful bacteria (e.g., Staphylococcus), making it a natural preservative in some formulations and supporting immune health by reducing bacterial load.


Depression Relief (for Cerebral Dysfunction)

Studies show it may reduce depression severity in individuals with brain-related dysfunction (e.g., vascular dementia), as it improves brain blood flow and neurotransmitter balance.


Usage


Medicinal Applications

Used in prescription and over-the-counter medications for:

Dementia and Alzheimer’s disease (adjuvant therapy).

Peripheral vascular disease (to improve circulation).

Mild depression (in patients with cerebral dysfunction).


Health Supplements

Formulated into capsules, tablets, or liquid extracts for daily cognitive and cardiovascular support. It pairs well with Bacopa Monnieri Extract for enhanced brain health benefits and with omega-3 fatty acids for heart wellness.


FAQ


Is Ginkgo Biloba Leaf Extract safe for long-term use?

Yes, when used at recommended doses. Our extract’s low ginkgolic acid content (≤1.43ppm) minimizes the risk of side effects (e.g., gastrointestinal upset). We recommend consulting a healthcare provider for long-term use, especially for individuals on blood thinners.


What is the particle size of the extract?

99% of the powder passes through an 80-mesh screen (tested via 80 Mesh Screen Visual method), ensuring uniform blending in supplements and medications.


How is the extract’s ash content controlled?

Ash content is tested via USP methods (2g/525°C/3hrs) and kept ≤1.0% (our latest batch tested at 0.30%). This ensures minimal mineral impurities and high extract purity.
