2.Why use Ginkgo Biloba Bulk Powder?

Ginkgo biloba powder is extracted from ginkgo biloba leaves and has the functions of promoting blood circulation, removing blood stasis, dredging collaterals and relieving pain. Clinical pharmacology shows that Ginkgo biloba extract can improve blood circulation, expand cardiovascular and cerebrovascular, inhibit platelet aggregation, and has a certain effect on lowering blood lipids, blood pressure, and blood viscosity. It is widely used to treat cardiovascular and cerebrovascular diseases, such as cerebral thrombosis, cerebral infarction, coronary heart disease, etc. Clinically, medicines with ginkgo extract as the main ingredient, as well as patent medicines and injections, are widely used in clinical treatment and have very good effects.

3.How to make ginkgo leaf powder?

1). Preparation

Take fresh ginkgo leaves, wash them, dry them, bake them in an oven at 70°C for 9 hours (depending on the moisture content of the sample, can be 8-12 hours), take them out and place them in a drying oven for cooling, and crush them through a 60-mesh sieve with a crusher. The powder is stored in a brown jar.

2). Extraction

Prepare a 60% ethanol solution (take 640mL of 95% ethanol and 360mL of purified water to make a 60% ethanol solution). Take 100g of ginkgo leaf powder in 700mL of 60% ethanol, heat it to 60℃~70℃ in a water bath, extract for 2h, stir every 10min, filter with gauze, add 700mL of 60% ethanol to the residue, and continue at 60℃~70℃ Extract for 2h, stir once every 10min, filter with gauze, and combine the extracts. Do parallel experiments at the same time.

3). Suction filtration 

First use gauze to coarsely filter to remove large particles and increase the suction speed. Install the suction filter equipment, add a small amount of extract into the Buchner funnel for suction filtration, because the ginkgo leaves contain colloidal sediments, the filter paper is easy to cause blockage, resulting in a drop in the suction filtration speed, so the filter paper should be replaced frequently. After suction filtration, take the filtrate and discard the residue.

4). Distillation and concentration 

Install distillation and concentration equipment, draw a large amount of ethanol solution in the filtrate, and use a distillation device for ethanol concentration. A certain amount of ethanol also has a bactericidal effect. When determining the antibacterial effect of the extract, the interference of the ethanol solvent should be eliminated as much as possible to make the ethanol completely volatilize. In order not to destroy the effective ingredients in the extract, the temperature of the water bath is controlled at 60℃~70℃, and the boiling point of 95% ethanol is about 75℃, so the distillation speed is slow and the time is long. A simple method can be used to directly heat in a water bath to volatilize ethanol in the air. The disadvantage of this method is that ethanol cannot be recovered. The final extract is a part of precipitation extract, the color is dark brown viscous.

5). Dry

Because the concentrated extract still contains part of ethanol and water, vacuum drying method is used, and the temperature is controlled between 60℃~70℃, and the boiling point is reduced by increasing the vacuum degree to remove the final ethanol and part of the remaining water. If conditions permit, freeze-drying can also be used. In addition to flavonoids and lactones, the extract at this time also contains a certain amount of impurities.
