The name Ginkgo is derived from a wrong transcription
of the Japanese name Yin-Kwo that means silver fruit, while the
name biloba derives from the bilobed shape of its leaf.
Among the pharmacological active constituents
those compounds with great importance are the flavonoids (ginkgo
flavonol glycosides) and the terpene trilactones (ginkgolides and
bilobalide). Different kind of flavonoids has been isolated from
the ginkgo extracts. Those of therapeutic interest are glycosyl
derivitives of quercitin and kaempferol respectively. Kaempferol
is considered particularly relevant for the therapeutic efficacy.
Therapeutic
Applications: Ginkgo biloba
extract is believed to have a regulating effect on the entire vascular
system of veins, arteries and capillaries. The most common usage

Gingko biloba is also used to counteract a number of conditions
such as vascular insufficiency and tinnitus and has also been indicated
in the treatment of intermittent claudication (pain while walking).
Recent studies have also indicated the potential use of Ginkgo biloba
in the treatment of AlzheimerÕs disease. Ginkgo biloba extract is
also a free radical scavenger and powerful antioxidant.
