Abstract
Extracts from the leaves of Ginkgo biloba trees have been used therapeutically for centuries in traditional Chinese medicine, and in modern Chinese pharmacopoeias both the leaves and fruits are recommended for treating problems of heart and lungs. EGb 761 is a dry, powdered extract prepared from Ginkgo biloba leaves. It is a standardized mixture of several different chemical constituents; its two major classes of compounds are flavonoid glycosides and terpenoids (Drieu 1986; DeFeudis 1991). The flavonoid fraction is mainly composed of three flavonols: quercetin, kaempferol, and isorhamnetin, which are linked to a sugar(DeFeudis 1991). The terpenoid fraction is composed of ginkgolides and bilobalides(Drieu 1988). It also contains some organic acids, which help make it water-soluble(Drieu 1986).
