Ginkgo leaf extract is the dried leaf extract of Ginkgo (Ginkgobiloba L.), a plant of the Ginkgoaceae family. Its main components are flavonoids and terpene lactones. It has multiple health functions and is widely used in food and cosmetics.

Chemical composition

The chemical composition of Ginkgo biloba leaves is very complex, and more than 140 compounds have been isolated from them. Flavonoids and terpene lactones are the two main active ingredients of Ginkgo biloba leaves. Ginkgo flavonoids, also known as monoflavonoids, are mainly composed of glycosides of kaempferol, quercetin and isorhamnetin; Ginkgo terpene lactones belong to terpene compounds, composed of terpene lactones and diterpene lactones, and are mainly bilobalide and ginkgolide. In addition, it also contains polyprenols, organic acids, polysaccharides, amino acids, phenols and trace elements.

Eye protection tablets: Compound lutein, improve retinal microcirculation (clinical 8-week visual clarity ↑28%)

3. Anti-aging direction of cosmeceuticals

Antioxidant essence: 1% ginkgo extract inhibits MMP-1 collagen degradation and reduces UV wrinkle formation

Medical Uses

The biological activities of Ginkgo biloba extract are varied. In animal studies, Ginkgo biloba extract appears to reduce glucose utilization in brain areas that regulate somatosensory processing and alertness, inhibit stress-induced corticosteroid release, and prevent age-related changes in the mouse hippocampus. Other animal studies have shown that Ginkgo biloba extract can inhibit nitric oxide, cause vasodilation, reversibly inhibit brain monoamine oxidase A and B, and may scavenge free radicals, which may be mediators of lipid peroxidation and cell damage in Alzheimer's disease. Other studies have found that Ginkgo biloba extract has antioxidant effects and can inhibit acetylcholinesterase.
