Dried Ginkgo leaves and fruits contain flavonoic compounds (ginkgo-flavon glucoside) in which the aglycon part is a flavonol (quercetin, kaempferol, and isorhamnetin), the sugar part is glucose and rhamnose. There is also a small amount of proanthocyanidin. The group of terpenes includes ginkgolite (which are diterpenes) and bilobalite (sesquiterpene) with a bitter taste. Besides the above two active ingredients, ginkgo leaves also contain some organic acids such as hydroxykinurenic, kinurenic, parahydroxybenzoic, vanillic. Currently, the extract of Ginko biloba from the leaves of the Ginkgo tree is used to make preparations for the treatment of dementia.
