Why Ginkgo biloba can be used for medical treatment?

Kawamura( 1928) separated three compounds from ginkgo meat: ginkgolic acid, ginkgolic acid and ginkgolic acid.

Furukawa (1933) calculated the structural formulas of these three compounds. The main function of Ginkgo biloba leaves is anti-tuberculosis.

Zhu (1943) believes that Ginkgo biloba has a convulsive effect on mice through chemical and toxicological studies.

Lin et al. (1949) thought that white fruit juice, white pulp bilobanol, especially bilobalic acid, could inhibit the growth of bacteria in test tubes, while bilobanol could promote the growth of mycobacteria. In addition, Ginkgo biloba leaves have different degrees of inhibition on all kinds of bacteria. The antibacterial activity of pulp is stronger than that of peel.

Cao Renlie (1957) also reported that its aqueous solution had different degrees of inhibition on several tinea fungi. Many researchers have extracted ginkgol A from fresh Ginkgo biloba leaves, which has paralyzing effect on isolated rabbit intestine, contracting isolated uterus, temporarily lowering blood pressure and increasing vascular permeability.

Ginkgo biloba leaves also have important medicinal value. Up to now, there are more than 60 kinds of Ginkgo biloba extract with known chemical components/kloc-0. There are mainly flavonoids, terpenoids, phenols, alkaloids, polyisoprene, quinic acid, linoleic acid, python oxalic acid, ascorbic acid, α-hexenal, bilobanol, bilobanone and so on. Among them, theaflavins are the main ones, and the contents of four kinds of biflavonoids (theaflavins, ginkgetins, isoginkgetins and ginkgetins) in the crude extract of Ginkgo biloba leaves are the highest in autumn leaves. Autumn leaves 17.2mg/g, summer leaves 4.4 mg/g. In 1960s, Institute of Botany, Chinese Academy of Sciences and other units developed Shuxuening injection with Ginkgo biloba leaves, which had certain curative effects on coronary heart disease, angina pectoris and cerebrovascular diseases.

Ginkgo biloba leaves have the effect of treating senile dementia.

According to Xinhua News Agency, Rio de Janeiro, April 2:

According to media reports here, researchers at the Federal University of Sao Paulo in Brazil found that Ginkgo biloba, an ancient plant from China, can help treat Alzheimer's disease and delay the aging of the human brain.

The research team led by Dr. Santos, a famous Brazilian neurologist, began to study the treatment of patients with advanced Alzheimer's disease several years ago. The results show that Ginkgo biloba leaves have the function of smoothing blood vessels, and it has an unattainable effect in delaying brain aging and enhancing the memory of the elderly.

The research team selected 48 Alzheimer's patients aged 60-70 in the experiment. These patients were divided into two groups. The first group took 80 mg of refined ginkgo juice every day, and the other group took a placebo. Six months later, the researchers found that patients who took placebo got worse, while patients who took ginkgo juice improved their memory, attention and ability to complete complex movements.
