BOTANICAL NAME

 

Ginkgo biloba L.
Plant Family: Ginkgoaceae

 

OVERVIEW

 

Ginkgo, the oldest living species of plant on earth, is more than 225 million years old. In this U.S. it has been one of the ten best selling herbs for more than 5 years and a standardized extract of ginkgo leaf is presently one of the most frequently used plant-based medicines in Europe.

Recent research into the plant has discovered a range of active compounds in the leaves and this has excited a lot of interest in the health-promoting potential of the plant. The leaves contain ginkgolides, these are compounds that are unknown in any other plant species. The leaves are best harvested in the late summer or early autumn just as they begin to change color. They are dried for later use.

Ginkgo leaf promotes healthy blood circulation.*

 

USES AND PREPARATIONS

 

The leaves are considered "sweet" and have a gentle effect. They can be used in teas, capsules, and extracts.

 

CONSTITUENTS

 

Gibberellin, cytokinin-like substances, ginkgolic acid, bilobol, ginnol, aspartine, calcium.

 

HERBAL MISCELLANY

 

Native to China, the ginkgo tree is beautiful and unique, both aesthetically and biologically. Having lived for over 225 million years, the ginkgo is one of the oldest known species on the planet. Wild populations of ginkgo are rare, existing only in two known regions of the Zhejiang province in China. Nevertheless, ginkgoes are heavily cultivated across China and in some parts of the United States, with naturalized populations located in parts of Asia.

After the bombing at Hiroshima at the conclusion of World War 2, surveyors examined the effect of the blast on local plant populations. Throughout the devastation, six ginkgo trees survived the bombing, the closest of which still lives less than 1200 meters from the epicenter. This tree stands as an international symbol of resilience and the ginkgo itself is regarded as a "bearer of hope."

Remarkably hardy, ginkgo trees are slow to grow and can live over 1000 years. The female trees produce small globular fruits with a distinctive unpleasant odor. As such, many cultivators distribute only the male trees which do not produce the fruit.

Ginkgo Biloba Leaf Extract


Ginkgo folium
Ginkgo biloba bltter
Published July 19, 1994

Name of Drug

Dry extract (35 - 67:1) from Ginkgo biloba L. leaf [Fam. Ginkgoaceae], extracted with acetone/water. Active Ingredient Classification ASK No. 05939.

Composition of Drug

A dry extract from the dried leaf of Ginkgo biloba L. manufactured using acetone/water and subsequent purification steps without addition of concentrates or isolated ingredients.

The drug/extract ratio is 35 - 67:1, on average 50:1.

The extract is characterized by:

22 - 27 percent flavonone glycosides, determined as quercetin and kaempferol, including isorhamnetin (via HPLC) and calculated as flavones with a molar mass of MMr = 756.7 (quercetin glycosides) and Mr = 740.7 (kaempferol glycosides); 5 - 7 percent terpene lactones, of which approximately 2.8 - 3.4 percent consists of ginkgolides A, B, and C, as well as approximately 2.6 - 3.2 percent bilobalide; below 5 ppm ginkgolic acids.

The given ranges include manufacturing and analytical variances.

Pharmacological Properties, Pharmacokinetics, Toxicology  

The following pharmacological effects have been established experimentally:

  • Improvement of hypoxic tolerance, particularly in the cerebral tissue.
  • Inhibition of the development of traumatically or toxically induced cerebral edema, and acceleration of its regression.
  • Reduction of retinal edema and of cellular lesions in the retina.
  • Inhibition in age-related reduction of muscarinergic cholinoceptors and 2-adrenoceptors as well as stimulation of choline uptake in the hippocampus.
  • Increased memory performance and learning capacity.
  • Improvement in the compensation of disturbed equilibrium.
  • Improvement of blood flow, particularly in the region of microcirculation.
  • Improvement of the rheological properties of the blood.
  • Inactivation of toxic oxygen radicals (flavonoids).
  • Antagonism of the platelet-activating factor/PAF (ginkgolides).
  • Neuroprotective effect (ginkgolides A and B, bilobalide).

 

The pharmacokinetics have been investigated both in animal experiments and in trials involving humans. An absorption rate of 60 percent was found in rats for a radioactively labeled extract (as specified under Composition of Drug). In humans after application of an extract specified as above, absolute bioavailability was 98 - 100 percent for ginkgolide A, 79 - 93 percent for ginkgolide B and at least 70 percent for bilobalide.

Both the acute and the chronic toxicity of an extract as specified under Composition of Drugis very low; accordingly, the LD50in the mouse was 7725 mg/kg body weight after oral application and 1100 mg/kg body weight after intravenous application.

Investigations with this extract as specified above showed no effects which were either mutagenic, carcinogenic, or toxic to reproduction.

No evaluation was performed on the transferability of the experimental results to extracts other than those investigated.

[Ed.note:This statement refers to the fact that only a few proprietary ginkgo extracts were used in the studies upon which this monograph is based. Whether these results can be extrapolated to other ginkgo extracts is uncertain.
