Embodiment 1
[0018] Embodiment 1: Industrialized production of the effective part of windproof polyacetylene alcohol
[0019] 1.1 Raw materials and reagents
[0020] Raw material: Fangfeng, root of Umbelliferae plant Fangfeng, origin Inner Mongolia.
[0021] Reagents: ethanol, water, D101 macroporous adsorption resin.
[0022] 1.2 Production process
[0023] (1) Extraction of windproof polyacetylene alcohol
[0024] Take 1.0 tons of Fangfeng, crush it, and place it in an extraction tank. Ultrasonic extraction was performed twice with 70% ethanol at a solid-liquid ratio of 1:10, each time for 0.5 hours. The ethanol extract was collected, and the ethanol was recovered under reduced pressure to obtain a concentrated solution. Add 10 times the amount of water to disperse and dissolve the concentrate, centrifuge, and use the supernatant as the sample solution for further separation.

Embodiment 2
[0031] Example 2: Industrialized production of effective parts of ginseng polyacetylene alcohol
[0032] 1.1 Raw materials and reagents
[0033] Raw materials: 4-year-old ginseng whiskers, dried fibrous roots of Araliaceae ginseng, from Fusong.
[0034] Reagents: ethanol, water, D101 macroporous adsorption resin.
[0035] 1.2 Production process
[0036] (1) Extraction of ginseng polyacetylene alcohol
[0037] Take 1.0 tons of ginseng silk, crush it, and place it in an extraction tank. Ultrasonic extraction was performed twice with 85% ethanol at a solid-liquid ratio of 1:10, each time for 0.5 hours. The ethanol extract was collected, and the ethanol was recovered under reduced pressure to obtain a concentrated solution. Add 10 times the amount of water to disperse and dissolve the concentrate, centrifuge, and use the supernatant as the sample solution for further separation.

Embodiment 3
[0044] Example 3: Industrialized production of effective fractions of carrot polyacetylene alcohol
[0045] 1.1 Raw materials and reagents
[0046] Ingredients: fresh carrots.
[0047] Reagents: ethanol, water, D101 macroporous adsorption resin.
[0048] 1.2 Production process
[0049] (1) Extraction of carrot polyacetylene alcohol
[0050] Take 1.0 tons of carrots, crush them, and place them in an extraction tank. Ultrasonic extraction was performed twice with 95% ethanol at a ratio of solid to liquid of 1:10, each time for 40 minutes. The ethanol extract is collected, the ethanol is recovered under reduced pressure until the concentrate has no alcohol smell, and the carrot polyacetylene alcohol extract is obtained.
[0051] (2) Sample loading
[0052] The pretreated D 101 macroporous resin was wet-packed, and 5 times the column volume of carrot polyacetylene alcohol extract was passed through the resin for dynamic adsorption at a constant flow rate.
