Embodiment 1
[0037] Using method A, take the sun-dried coriander root tubers and crush them to 100 mesh, stir with 3 times the volume of 50% ethanol in a water bath at 30°C for 8 hours, filter with suction to obtain a crude extract, repeat the extraction 4 times, and combine the filtrates. Concentrate the filtrate by rotary evaporation under reduced pressure at 30°C, dissolve the obtained extract in hot water at 30°C, the extract volume / water volume is 1:2.5, add petroleum ether at a volume ratio of 1:1 for extraction, and remove fat-soluble impurities. Repeated extraction with n-butanol for 3 times, recovering n-butanol under reduced pressure to obtain crude total saponins. The obtained crude total saponins were dissolved in a small amount of anhydrous methanol, and then ethyl acetate (1:0.5 by volume ratio) was added dropwise, stirred and mixed evenly, and total saponins were precipitated. The treatment was repeated 5 times, and the precipitated total saponins were collected and freeze-d...
Embodiment 2
[0039] Using method A, the sun-dried coriander root tubers were crushed to 40 mesh, stirred with 6 times the volume of 75% ethanol in a water bath at 80°C for 6 hours, suction filtered to obtain a crude extract, repeated extraction twice, and the filtrates were combined. Concentrate the filtrate by rotary evaporation under reduced pressure at 70°C, dissolve the extract in hot water at 70°C, the volume of the extract / water volume is 1:2, add petroleum ether at a volume of 1:2 for extraction, and remove fat-soluble impurities. Repeated extraction with n-butanol for 5 times, and recovering n-butanol under reduced pressure to obtain crude total saponins. The obtained crude total saponins were dissolved in a small amount of anhydrous methanol, and then ethyl acetate (1:0.8 by volume ratio) was added dropwise, stirred and mixed evenly, and total saponins were precipitated. Repeat the treatment 5 times, collect the precipitated total saponins, and dry under reduced pressure and vacuu...
Embodiment 3
[0041] Using method A, take the sun-dried coriander root tubers and crush them to 200 mesh, stir with 10 times the volume of 95% ethanol in a water bath at 65°C for 8 hours, filter with suction to obtain a crude extract, repeat the extraction 4 times, and combine the filtrates. Concentrate the filtrate by rotary evaporation under reduced pressure at 65°C, dissolve the extract in hot water at 55°C, the volume of the extract / water volume is 1:2, add petroleum ether at a volume of 1:1 for extraction, and remove fat-soluble impurities. Repeated extraction with n-butanol for 6 times, and recovering n-butanol under reduced pressure to obtain crude total saponins. The obtained crude total saponins were dissolved in a small amount of anhydrous methanol, and then ethyl acetate (1:0.5 by volume ratio) was added dropwise, stirred and mixed evenly, and total saponins were precipitated. Repeat the treatment 5 times, collect the precipitated total saponins, and dry under reduced pressure an...
