There are a number of compounds which may be isolated from Ginkgo biloba. Terpene lactones account for 6% and Ginkgo-flavone glycosides account for 24%. Ginkgo-flavone glycosides inhibit a substance called Platelet Activating Factor (PAF), which is responsible for platelet aggregation and clot formation. PAF is also involved in many inflammatory and allergic reactions. These substances are shown to increase arterial blood supply, especially to the brain, enhancing tissue utilisation of oxygen and glucose.
