Chemical Composition: Ginkgo leaves have a very complex chemical composition, with over 140 compounds isolated. Flavonoids and terpene lactones are the two main active components. Ginkgo flavonoids, also known as monoflavonoids, are mainly composed of glycosides of kaempferol, quercetin, and isochemicalbook rhamnoside. Ginkgo terpene lactones belong to the terpene class of compounds, consisting of terpene lactones and diterpene lactones, with ginkgolides and ginkgolides being the main components. In addition, they also contain polypentenols, organic acids, polysaccharides, amino acids, phenols, and trace elements.
Uses Ginkgo biloba extract exhibits a variety of biological activities. In animal studies, it appears to reduce glucose utilization in brain regions regulating somatic sensory processing and alertness, and inhibit stress-induced corticosteroid release, preventing age-related changes in the mouse hippocampus. Other animal studies have shown that ginkgo biloba extract can inhibit nitric oxide, induce vasodilation, reversibly inhibit brain monoamine oxidases A and B, and may also scavenge free radicals, which may mediate lipid peroxidation and cell damage in Alzheimer's disease. Further research has found that ginkgo biloba extract possesses antioxidant properties and can inhibit acetylcholinesterase.
