Abstract
Ginkgo biloba extract is a well-defined and complex product prepared from green leaves of Ginkgo biloba. The leaves are harvested from trees growing in plantations in South Korea, Japan, and France. The mode of culture, harvesting, and extraction are perfectly standardized and controlled. Analysis of Ginkgo biloba extract makes it possible to confirm that undesirable substances have been eliminated and to measure the amount of active principles. The extract contains flavonoid substances, such as the Ginkgo-flavone glycosides and terponoids which are characteristic of Ginkgo and have a unique structure (ginkgolides, bilobalide).Keywords
