Ginkgo biloba--an appraisal.
Ginkgo biloba has been used in traditional Chinese medicine for about 5000 years. A standardized preparation, EGb 761 has been recently prepared. The pharmacologically active constituents, flavonol glycosides and the terpene lactones are standardized. The terpene lactones comprise of ginkgolides A, B, C and bilobalides. The extract scavenges excess free radicals and pretreatment with EGb 761 re...
متن کاملRegional distribution of Ginkgo biloba-induced c-Fos immunoreactivity.
A growing literature supports the notion that Ginkgo biloba has cognitive enhancing and anxiolytic properties; however, its effects on neuronal populations have yet to be characterized. The present study used c-Fos immunoreactivity (Fos-IR) to characterize functional activity in selected brain regions following administration of a standardized Ginkgo biloba extract. Because Ginkgo is typically ...
متن کاملGinkgo biloba: local experiences.
Ginkgo biloba (EGb 761) as a phytotherapeutic agent used in otoneurology, psychiatry, and ophthalmology. We studied the efficacy of therapy with EGb 761 in 72 patients (44 male and 28 female) with chronic cochleovestibular disorders. We used pure-tone audiology, measuring pure-tone average, speech reception threshold, and speech discrimination score. Then we used craniocorpography to measure la...
متن کاملPolyphenols from Ginkgo biloba
By Sephadex LH-20 gel chromatography of an extract from Gingko biloba leaves, polymeric proanthocyanidins were eluted after the fractions of flavonol glycosides and biflavone glycosides. A purified proanthocyanidin polymer accounted for 86.6% of the total proanthocyanidins, and for 37.7% of the total antioxidant activity of this leaf extract. For structure elucidation, the polymer was submitted...
