Embodiment 1
[0050] The preparation method of a new barison glycoside compound in Gastrodia elata is as follows:
[0051] 1. Extraction: After crushing the dried Gastrodia elata medicinal material, add 50% ethanol solution with a volume 8 times the weight of the medicinal material, heat and reflux at 70°C for 3 times, each time for 2 hours, combine the extracts, and concentrate to obtain the total extract;
[0052] 2. Rough fractionation: after the total extract obtained from the above extraction is dissolved in water 10 times the weight of the total extract, the mass ratio of Gastrodia elata medicinal material to resin is 1:1, and the AB-8 macroporous adsorption resin is used to dissolve the total extract with water. , 20% ethanol solution, 70% ethanol solution, 95% ethanol solution gradient elution, each gradient elution has four retention volumes, collect the eluted part of 70% ethanol solution, and concentrate under reduced pressure at 60°C to obtain a crude extract;
[0053] 3. Refini...
Embodiment 2
[0056] The preparation method of a new barison glycoside compound in Gastrodia elata is as follows:
[0057] 1. Extraction: After crushing the dried Gastrodia elata medicinal material, add 50% ethanol solution with a volume 8 times the weight of the medicinal material, heat and reflux at 75°C to extract 3 times, each time for 2 hours, combine the extracts, and concentrate to obtain the total extract;
[0058] 2. Rough fractionation: after the total extract obtained from the above extraction is dissolved in water 10 times the weight of the total extract, the mass ratio of Gastrodia elata medicinal material to resin is 1:1, and the AB-8 macroporous adsorption resin is used to dissolve the total extract with water. , 20% ethanol solution, 70% ethanol solution, 95% ethanol solution gradient elution, each gradient elution has four retention volumes, collect the eluted part of 70% ethanol solution, and concentrate under reduced pressure at 60°C to obtain a crude extract;

Embodiment 3
[0062] The preparation method of a new barison glycoside compound in Gastrodia elata is as follows:
[0063] 1. Extraction: After crushing the dried Gastrodia elata medicinal material, add 50% ethanol solution with a volume 8 times the weight of the medicinal material, heat and reflux at 80°C for 3 times, each time for 2 hours, combine the extracts, and concentrate to obtain the total extract;
[0064] 2. Rough fractionation: after the total extract obtained from the above extraction is dissolved in water 10 times the weight of the total extract, the mass ratio of Gastrodia elata medicinal material to resin is 1:1, and the AB-8 macroporous adsorption resin is used to dissolve the total extract with water. , 20% ethanol solution, 70% ethanol solution, 95% ethanol solution gradient elution, each gradient elution has four retention volumes, collect the eluted part of 70% ethanol solution, and concentrate under reduced pressure at 60°C to obtain a crude extract;
