Action:
1.Ginkgo biloba is used for
cerebral insufficiency and Alzheimer's disease.
2.It also is used for peripheral
vascular insufficiency.
Ginkgo biloba extract and two
ingredients, bilobalide and ginkgolide B, are presented to the CSWG
as part of a review of botanicals being used as dietary supplements
in the United States. ( 1 of 3 adults in the United States are now
taking dietary supplements ). Sweeping deregulation of botanicals
now permits Ginkgo biloba extract to be sold as a dietary
supplement to a willing public eager to improve brain functioning
or promote radical scavenging activity.
Ginkgo biloba extract is a well
defined product, and it or its active ingredients, the ginkgolides,
especially ginkgolide B, and bilobalide, have clearly demonstrated
biological activity. It can be consumed in rather large doses for
an extended period of time.
Standardized ingredients of
Ginkgo biloba extract
The extract utilized in medicine is
standardized in a multi-step procedure designed to concentrate the
desired active principles from the plant. These extracts contain
approximately *4% flavone glycosides (primarily composed of
quercetin, kaempferol, and isorhamnetin) and 6% terpene lactones
(2.**3.4% ginkgolides A, B, and C, and 2.**3.2% bilobalide).
Ginkgolide B accounts for about 0.8% of the total extract, and
bilobalide accounts for about 3% of the extract. Other constituents
include proanthocyanadins, glucose, rhamnose, organic acids,
D-glucaric acid and ginkgolic acid (at most 5 ppm ginkgolic acids).
