specific Embodiment 1

[0050] Preparation: take fresh ginkgo leaves, wash them, dry them in the oven at 70°C for 9 hours (the time depends on the moisture content of the sample, it can be 8-12 hours), take them out and put them in a drying oven to cool, and crush them with a grinder to pass 80 mesh Sieve, and store the powder in a brown jar.

[0051] Extraction: Prepare 60% ethanol solution (take 640mL95% ethanol and 360mL pure water to make 60% ethanol solution). Take 100g of ginkgo leaf powder in 700mL of 60% ethanol, heat to 60°C-70°C in a water bath, extract for 2 hours, stir once every 10 minutes, filter with gauze, add 700mL of 60% ethanol to the residue, and continue at 60°C-70°C Extract for 2 hours, stir once every 10 minutes, filter through gauze, and combine the extracts. Do parallel experiments at the same time.

[0052] Suction filtration: first use gauze to coarsely filter to remove large particles and precipitate, so as to increase the speed of suction filtration. Install suction fi...

specific Embodiment 2

[0057] Pick 1000g of fresh and tender ginkgo leaves, wash them, dry them in the oven at 70°C for 10 hours, take them out and put them in a drying oven to cool them, crush them through a 60-mesh sieve with a pulverizer, store the powder in a brown wide-mouth bottle and prepare 60 %weak. Take 1000g of ginkgo leaf powder in 7000mL of 60% ethanol, heat it to 60℃~70℃ in a water bath, extract for 2 hours, stir once every 10min, filter with gauze, add 7000mL of 60% ethanol to the residue, and continue at 60℃~70℃ Extract for 2 hours, stir once every 10 minutes, filter through gauze, and combine the extracts. Do parallel experiments at the same time. First use gauze to filter coarsely to remove large particles and precipitate, so as to increase the speed of suction filtration. Install suction filtration equipment, add a small amount of extract solution to the Buchner funnel for suction filtration, because ginkgo leaves contain colloidal sediment, the filter paper is easy to cause blo...

specific Embodiment 3

[0058]Pick 500g ginkgo leaves, wash and dry them in an oven at 70°C for 9 hours, take them out and cool them in a drying oven, crush them through a 60-mesh sieve with a grinder, and store the powder in a brown jar to prepare 60% ethanol Solution (take 640mL95% ethanol, 360mL purified water to make 60% ethanol solution). Take 500g of ginkgo leaf powder in 3500mL of 60% ethanol, heat to 60°C-70°C in a water bath, extract for 2 hours, stir once every 10 minutes, filter with gauze, add 35,000mL of 60% ethanol to the residue, and continue at 60°C-70°C Extract for 2 hours, stir once every 10 minutes, filter through gauze, and combine the extracts. Do parallel experiments at the same time. First use gauze to filter coarsely to remove large particles and precipitate, so as to increase the speed of suction filtration.
