Ginkgo (Ginkgo biloba) is a well-known, slow-growing deciduous tree that is one of the oldest trees that exists; its plant parts have been used in traditional medicines since ancient times. The tree is native to China and has been introduced worldwide for ornamental and medicinal reasons. The main active components in ginkgo are found in the leaf, with the major chemicals consisting of: flavonoids (quercetin, kaempferol, and isorhamnetin), catechins, dehydrocatechins (proanthocyanidins), flavones (eg, ginkgetin, amentoflavone, bilobetin, sciadopitysin), terpenes, shikimic, vanillic, ascorbic, and p-coumaric acids.
Egg quality: Dietary supplementation of Fermented Ginkgo-leaves (FGL) may be a feasible means of producing eggs with lower cholesterol and higher PUFA contents, as showed by research conducted on laying hens.
Memory enhancement: Administering G. biloba extract to day old chicks demonstrated its use in establishing long-term memory.
