specific Embodiment 1
[0048] Preparation: Take fresh ginkgo leaves, wash them, dry them in the air, dry them in an oven at 70°C for 9 hours (the time depends on the moisture content of the samples, it can be 8 to 12 hours), take them out and cool them in a drying box, and grind them to 60 mesh with a pulverizer. Sieve and store the powder in a brown jar.
[0049] Extraction: prepare 60% ethanol solution (take 640 mL of 95% ethanol and 360 mL of purified water to prepare 60% ethanol solution). Take 100 g of ginkgo biloba powder in 700 mL of 60% ethanol, heat it to 60 ℃ ~ 70 ℃ in a water bath, extract for 2 hours, stir once every 10 min, filter with gauze, add 700 mL of 60% ethanol to the residue, continue at 60 ℃ ~ 70 ℃ Extraction for 2h, stirring once every 10min, filtering with gauze, and combining the extracts. Do parallel experiments at the same time.
[0050] Suction filtration: first coarsely filter with gauze to remove large particle precipitation, so as to improve the suction filtration sp...
specific Embodiment 2
[0055]Pick 2500g of fresh and tender ginkgo leaves, wash them, dry them in the air, dry them in a 70°C oven for 9 hours, take them out and place them in a drying oven to cool, pulverize them through a 60-mesh sieve, and store the powder in a brown jar to prepare 60 % ethanol solution (take 640 mL of 95% ethanol and 360 mL of purified water to make 60% ethanol solution). Take 1000 g of ginkgo biloba powder in 7000 mL of 60% ethanol, heat it to 60 ℃ ~ 70 ℃ in a water bath, extract for 2 hours, stir every 10 min, filter with gauze, add 7000 mL of 60% ethanol to the residue, continue at 60 ℃ ~ 70 ℃ Extraction for 2h, stirring once every 10min, filtering with gauze, and combining the extracts. Do parallel experiments at the same time. First, use gauze for coarse filtration to remove large particle precipitates to improve the suction filtration speed. Install a suction filtration instrument, and add a small amount of extracting solution to the Buchner funnel for suction filtration...
specific Embodiment 3
[0056] Pick 1200g ginkgo leaves, wash them, dry them in the air, dry them in a 70°C oven for 9 hours, take them out and cool them in a drying oven, crush them through a 60-mesh sieve with a pulverizer, and store the powder in a brown jar to prepare 60% ethanol. solution (take 640mL of 95% ethanol and 360mL of purified water to make a 60% ethanol solution). Take 500g of ginkgo biloba powder in 3500mL of 60% ethanol, heat it to 60℃~70℃ in a water bath, extract for 2 hours, stir every 10min, filter with gauze, add 35000mL of 60% ethanol to the residue, continue at 60℃~70℃ Extraction for 2h, stirring once every 10min, filtering with gauze, and combining the extracts. Do parallel experiments at the same time. First, use gauze for coarse filtration to remove large particle precipitates to improve the suction filtration speed. Install a suction filtration instrument, and add a small amount of extracting solution to the Buchner funnel for suction filtration. Because ginkgo leaves co...
