Example Embodiment
[0077] Example 1 Preparation method of arctiin and arctigenin
[0078] (1) Preparation of arctiin
[0079] ① Crude extraction of arctiin: After pulverizing the burdock seed, place it in a Soxhlet extractor and degrease it by refluxing petroleum ether at a boiling range of 60-90°C for 2 times. After degreasing, take it out and dry it, and extract it by refluxing with 60% 8 times ethanol for 2 times. 0.8h each time, the extract was concentrated under reduced pressure at 60°C to obtain a dark brown extract;
[0080] ②Refining of macroporous resin: add 15% ethanol to the dark brown extract, ultrasonically treat it for 15 minutes to make it just fully dissolve, filter and adjust to a solution with a concentration of about 5mg / mL, and pass it through the AB-8 type macroporous adsorption resin. The volume of the macroporous adsorption resin is 1 times the chemical solution, the flow rate is controlled to 1.5BV / h, the column diameter to height ratio is controlled to 1:5, the volume of the...

[0085] Example 2 Preparation method of arctiin and arctigenin
[0086] (1) Preparation of arctiin
[0087] ① Crude extraction of arctiin: After pulverizing the burdock seed, place it in a Soxhlet extractor and degrease it with petroleum ether at a boiling range of 60-90℃ for 4 times. After degreasing, take it out and dry it, and extract it with 80% 8 times ethanol under reflux for 4 times. Every 2h, the extract was concentrated under reduced pressure at 80°C to obtain a dark brown extract;
[0088] ②Refining of macroporous resin: add dark brown extract with 35% ethanol, ultrasonic treatment for 35 minutes to make it just fully dissolve, filter and adjust to a solution with a concentration of about 7mg / mL, pass it through AB-8 type macroporous adsorption resin, The volume of the macroporous adsorption resin is twice that of the chemical solution, the flow rate is controlled at 2.5BV / h, the column diameter-to-height ratio is controlled at 1:5, the volume of the resin is washed 3 tim...

[0093] Example 3 Preparation method of arctiin and arctigenin
[0094] (1) Preparation of arctiin
[0095] ① Crude extraction of arctiin: After pulverizing the burdock seed, place it in a Soxhlet extractor and degrease it by refluxing petroleum ether at a boiling range of 60-90℃ for 3 times. After degreasing, take it out and dry it, and extract it with 70% 8 times ethanol reflux for 3 times. For 1 hour each time, the extract was concentrated under reduced pressure at 70°C to obtain a dark brown extract;
[0096] ②Refining of macroporous resin: add 20% ethanol to the dark brown extract, ultrasonically treat it for 20 minutes to make it just fully dissolve, filter and adjust to a solution with a concentration of about 6mg / mL, and pass it through the AB-8 type macroporous adsorption resin. The volume of the macroporous adsorption resin is 1.5 times the volume of the chemical solution, the flow rate is controlled to 2BV / h, the column diameter to height ratio is controlled to 1:5, the ...
