Introduction and Application Fields of Ginkgo biloba Extract
1. Introduction to Ginkgo biloba Extract
Ginkgo biloba extract (GBE for short) is a mixture of active ingredients prepared from the dried leaves of Ginkgo biloba L. through extraction, purification and other processes. As an ancient gymnosperm, Ginkgo biloba is known as a "living fossil", and its medicinal value has long been recorded in traditional medicine. The development of modern extraction technology has enabled more efficient utilization of its active ingredients.
The main active components of GBE are flavonoids and terpenolactones (including ginkgolides A, B, C, J and bilobalide), which are the key to its physiological activities. In addition, the extract also contains a small amount of organic acids, polysaccharides and other components. Currently, commercially available Ginkgo biloba extracts are mostly subjected to standardized treatment to ensure the stable content of active ingredients. For example, the common EGb761 standard extract requires the content of flavonoids not less than 24% and terpenolactones not less than 6%.
