What is Ginkgo biloba extract ？

Ginkgo biloba extract is a dietary supplement derived from the leaves of the Ginkgo biloba tree, also known as the maidenhair tree. It has been traditionally used in Chinese medicine for centuries and is known for its medicinal properties. The extract is made by grinding the dried leaves of the Ginkgo biloba tree and then extracting the active compounds using a solvent, typically ethanol.

Ginkgo biloba extract contains a variety of compounds, including flavonoids, terpenoids and ginkgolides. The flavonoids and terpenoids are believed to be responsible for the extract’s antioxidant properties, while the ginkgolides are believed to be responsible for its anti-inflammatory effects.

Ginkgo biloba extract is commonly used to improve memory and cognitive function, particularly in older adults. It is also used to treat a variety of other health conditions such as anxiety, depression, tinnitus and age-related macular degeneration.

It is worth noting that Ginkgo biloba extract may interact with certain medications, such as blood thinners and antidepressants, so it’s important to talk to your doctor before taking it. Additionally, quality and composition of Ginkgo biloba extract may vary depending on the source and the extraction method, so it’s recommended to look for products that are standardized to contain a specific amount of flavonoids and terpenoids.

 

How to made Ginkgo biloba extract？

Ginkgo biloba extract is typically made by grinding the dried leaves of the Ginkgo biloba tree and then extracting the active compounds using a solvent. The most common solvent used is ethanol. Here’s a general overview of the process:

• Harvest and dry the leaves of the Ginkgo biloba tree: The leaves are harvested in the fall and dried in the sun or in a dehydrator.
• Grind the dried leaves: The dried leaves are ground into a fine powder using a grinder or a mortar and pestle.
• Extraction: The ground leaves are mixed with ethanol or another solvent to extract the active compounds. This is typically done by soaking the leaves in the solvent for several hours or days.
• Filtering: The mixture is filtered to separate the solvent-soluble compounds (the extract) from the insoluble plant material.
• Evaporation: The solvent is evaporated from the extract to obtain a concentrated liquid extract.
• Purification and standardization: The extract is purified and standardized to obtain a higher purity product and to ensure that it contains a specific amount of active compounds.

It’s worth noting that the exact process may vary depending on the manufacturer and the desired final product. Also, different methods such as supercritical fluid extraction can also be used to obtain the extract.
