Ginkgo biloba leaf extract is a kind of natural plant nutritional health ingredients extracted from the active ingredients of ginkgo biloba leaves through processing. Ginkgo tree is an evergreen tree, but its leaves turn yellow and gradually fall off in autumn, known as a "living fossil" for thousands of years. Ginkgo biloba extract is rich in ginkgolide substances, especially flavonoids (mainly phenolic flavonoids and isophenolic flavonoids), which have strong antioxidant, anti-aging, promote blood circulation, lower blood pressure and cholesterol and other health effects.
As a safe, natural and healthy plant extract, its multiple health functions and medicinal values have made it attract more and more attention.
Ginkgo biloba extract is made from the dried leaves of the ginkgo biloba tree. The leaves are first harvested and then dried, after which they are extracted using a solvent such as ethanol or water. The resulting extract contains a variety of compounds that are believed to have beneficial effects on the body, including flavonoids and terpenoids.
What are the main ingredients in ginkgo biloba folium extract?
The active ingredients in ginkgo biloba folium extract bulk that have been confirmed to exert unique pharmacological activities mainly include flavonoids and terpene lactones, which are important bases for the development of quality standards for Ginkgo biloba extracts and preparations.
1. Flavonoids
In 1941, Koichi Nakazawa isolated ginkgo biloba and determined the molecular formula as C32H22O10. Subsequently, Borke et al. isolated three biflavones from a mixture of ginkgo biloba by counter-current separation, and in addition to ginkgo biloba, there were isoginkgo biloba and In 1959, the structural formulae of these compounds were determined. Since the 1960s, the chemical composition of Ginkgo biloba has been studied more and more deeply and systematically in many countries using modern separation techniques. The amount of flavonoids in Ginkgo biloba is high, with 5.91% measured by UV spectrophotometry in Ginkgo biloba from Taixing, China. Flavonoids in Ginkgo biloba are composed of flavonoids and their glycosides, biflavones and catechins. So far, 40 flavonoids have been isolated, among which 28 flavonoids and glycosides are composed of quercetin, kaempferitin, isorhamnetin, poppy bark, lignan, caryophyllin and their mono-, di- and triosaccharide glycosides, including cinnamoyl flavonoid glycosides. Monoflavones are mainly glycosides formed by kaempferetin, quercetin and isorhamnetin with various glycosyl groups, which all contain 5, 7, 4′-trihydroxy groups and 3-hydroxyl groups attached to glycosyl groups, and the glycosyl groups can be monosaccharides, disaccharides and trisaccharides, mostly glucose and rhamnose.
2. Ginkgolide
Terpene lactone compounds are another important class of bioactive compounds in Ginkgo biloba extract for sale, and six terpene lactones have been isolated and are collectively referred to as ginkgolide. Ginkgo biloba terpene lactones are diterpenes and sesquiterpenes. The diterpenoids were isolated from the leaves and bark of Ginkgo biloba by Nakanishi et al. Sesquiterpenes are another class of compounds related to the diterpene ginkgolide structure, also known as bilobalide, isolated by Weinges from Ginkgo biloba.
Since the 1960s, foreign research on terpene lactones, a unique component of Ginkgo biloba, has gradually deepened, shifting from chemical and pharmacological research to medical research.
1. Improved cognitive function
Ginkgo biloba extract powder bulk is often used as a natural cognitive enhancer and is believed to help improve memory and concentration.
① Improve learning memory, promote the learning memory process of elementary school students and improve memory reproduction.
② Neuroprotective effect: reduce damage to the auditory nerve, clinically GbE has a significant improvement effect on deafness and tinnitus caused by ischemia, metabolic disorders, etc.
③ Effects on aging, dementia and brain dysfunction: It can increase the density of muscarinic receptors in the hippocampus of aged rats, and has a significant improvement effect on brain dysfunction, brain insufficiency, insomnia and memory impairment in old age.
2. Antioxidant effects
Ginkgo biloba extract powder has strong antioxidant properties, which can help protect the body from damage caused by free radicals.
So far, there are many theories about the mechanism of aging, but among the many theories of aging, the free radical theory of aging occupies an important position. In living organisms, redox reactions, roughly 2% to 5% of oxygen will produce superoxide radicals, which react with proteins, fats and nucleic acids to destroy the chemical structure of intracellular life substances, interfere with cellular functions and cause damage to the organism. Ginkgo biloba extract contains flavonoids and bitter lactones, both of which have antioxidant and free radical scavenging effects, and aging is related to free radical damage, so if people can drink beverages made of ginkgo biloba extract powder bulk or ginkgo biloba tea for a long time, it is good for delaying aging and prolonging life.
3. Anti-fatigue and hypoxia tolerance
When people feel general weakness and a temporary reduction in their ability to work after strong physical work or heavy exercise, the phenomenon is called locomotor fatigue. Fatigue is a self-protective response to prevent life-threatening overexertion of the organism. It arises to remind people that they should reduce the intensity of work and discontinue exercise to avoid damage to the body. Causes of fatigue: First, due to strong physical activity, the content of adenosine triphosphate (ATP) in the muscle is reduced, and creatine phosphate is consumed in large quantities. Secondly, due to the high intensity activity, the muscle does not get enough oxygen, and under the condition of hypoxia, glycolysis produces lactic acid, and a large amount of lactic acid accumulates in the muscle, so that the activity of ATPase and other enzymes decreases, as well as disrupting the ion balance inside and outside the cell, which finally leads to a decrease in muscle strength. The ginkgolide contained in Ginkgo biloba has the ability to generate ATP, which can antagonize the reduction of ATP caused by hypoxia. Flavonoids can dilate blood vessels, speed up systemic blood flow, increase oxygen supply, thus reducing the accumulation of lactic acid produced by anaerobic glycolysis and preventing the appearance of fatigue. Therefore, Ginkgo biloba drink is a kind of functional drink that can resist fatigue and hypoxia and enhance physical strength.
4. Anti-thrombotic, improve microcirculation, and prevent cerebral hemorrhage
It is generally believed that after coronary artery atherosclerosis, blood coagulation increases, platelets adhere to the artery wall and form thrombus, which can block the main part of the coronary artery of the heart and cause myocardial necrosis in the corresponding blood supply area, thus producing acute myocardial infarction. The flavonoids extracted from Ginkgo biloba can dilate coronary vessels, improve vascular endings and cerebral circulation, and ginkgo bitter lactone can inhibit platelet activating factor. In addition, mistletoe significantly inhibits platelet aggregation, which selectively binds to the thrombus on the blood vessel wall and finally creates an antithrombotic effect. The flavonoids of Ginkgo biloba scavenge the production of free radicals in the organism, thus also preventing abnormal blood rheology.
1. Whitening and antioxidant
Ginkgo biloba extract contains flavonoids that can effectively scavenge the free radicals present in the body and reduce the rate of lipid peroxide formation. Research shows that Ginkgo biloba extract also has superoxide dismutase (SOD) activity, which is known to be an excellent free radical scavenger; Ginkgo biloba flavonoids can protect skin cells from the effects of excessive oxidation of oxygen free radicals and enhance the anti-aging properties of the skin; Ginkgo biloba lactones can accelerate metabolism, improve blood circulation and tone the skin. Therefore, ginkgo biloba extract added to cosmetics can moisturize the skin, make it lustrous and reduce melanin formation. The combination of Ginkgo biloba extract with vitamin E and skin absorption enhancers such as propylene glycol and parsley ketone is more effective.
