Flavonoids and terpene lactones are the main bioactive compounds present in Ginkgo extracts. Flavonoids (such as quercetin, kaempferol, and isorhamnetin) are known for their antioxidant properties and have been studied for potential benefits in supporting cardiovascular health and improving blood flow. They also possess anti-inflammatory effects.
Terpene lactones, specifically ginkgolides and bilobalide, are believed to have neuroprotective effects and are known for their ability to enhance cerebral blood flow and protect nerve cells from damage. They are often associated with the cognitive and memory-enhancing properties of Ginkgo.
