Ginkgo Extract Flavones Introduction

Ginkgo Biloba Extract, also called EGB 761, is a standard extract of Ginkgo Biloba leaves. It contains 24% flavone glycosides (primarily quercetin, kaempferol and isorhamnetin) and 6% terpene lactones (2.8-3.4% ginkgolides A, B and C, and 2.6-3.2% bilobalide).

The main components of Ginkgo are flavonoids and terpene (tie) lactones. Ginkgo flavonoids have the effects of dilating blood vessels, inhibiting platelet activating factors, and regulating blood lipids. They can be used to regulate cardiovascular and cerebrovascular diseases, vascular dementia, etc.

The main functional component of Ginkgo biloba is ginkgo flavonoids. Ginkgo flavonoids, also known as ginkgo biflavonoids and ginkgo biflavonoids, are not a single substance, but a variety of biflavonoids with similar structures.

Research reports indicate that flavonoids have antioxidant effects and protect the body from damage by free radicals and unstable molecules. Free radicals and unstable molecules can damage body tissues and healthy cells, making people prone to illness. The causes of free radicals may come from genetic mutations, diseases, aging or environmental pollution, etc. Antioxidants can prevent the formation of free radicals and make the body healthier.

Benefits of Ginkgo Extract Flavones

Ginkgo Biloba Extract has antioxidant propert, Ginkgo Biloba Extract is widely used in food additives, functional drink and cosmetics.

Inhibit Platelet Aggregation

Ginkgo flavonoids administered in vivo inhibit both ADP- and collagen-induced platelet aggregation. It also inhibits collagen-induced platelet deformation, slows down the maximum degree of platelet aggregation, and inhibits thrombosis.

Adjust Blood Lipids

Ginkgo flavonoids can significantly increase high-density lipoprotein (HDL), oppose platelet activating factors, reduce blood lipids, improve microcirculation, and inhibit coagulation. These have significant effects on the prevention and treatment of hypertension.

Improve Cerebral Circulation and Protect The Brain

GBE can reduce cerebrovascular resistance, improve cerebral circulation, increase cerebral blood flow, improve brain nutrition, help improve memory and brain dysfunction or age-related central nervous system dysfunction, and has a protective effect on the brain and blood-brain barrier.

Anti-atherosclerotic Effect

Ginkgo flavonoid glycosides have a protective effect on human cytomegalovirus (HCMV) infection and promote the occurrence and development of atherosclerosis. Ginkgo flavonoid glycosides can inhibit the abnormal proliferation of HVMV-infected HUVEC304 cells and the reduction of NO secretion, and have certain preventive and therapeutic effects on atherosclerosis.

Regulate Blood Sugar

In medicine, Ginkgo extract has been used to replace insulin for diabetic patients. This shows that Ginkgo has the function of insulin to regulate blood sugar. Many glucose tolerance tests have proven that Ginkgo extract can regulate blood sugar and improve insulin resistance, thereby reducing insulin. Antibodies and enhanced insulin sensitivity have obvious effects.
