Embodiment 1
[0041] a. Take 1 kg of Gurixiang medicinal material, dry and pulverize it, put it in an extraction container, add 4L of 95% ethanol to soak for 0.5h, heat and reflux for extraction for 1.5h, filter, and collect the filtrate. Add 5 L of 95% ethanol to the dregs, extract for 1.0 h; filter, and collect the filtrate; add 4 L of 95% ethanol to the dregs, extract for 1.0 h; filter, and collect the filtrate. Combine the filtrates for 3 times, recover ethanol until it has no alcohol smell, and concentrate to obtain ethanol extract A;
[0042] b. Cool down the temperature of the ethanol extract A to below 0°C, then add ice water with ice cubes to the ethanol extract A, and grind continuously during the melting of the ice cubes to dissolve the ethanol extract A to form a suspension; control The temperature of the suspension is below 10°C, then extract and wash with petroleum ether, remove the components dissolved in petroleum ether, discard the petroleum ether extract, and the rest is e...
Embodiment 2
[0045] a. Take 1kg of Gurixiang medicinal material, dry and crush it, put it in an extraction container, add 8L of 75% ethanol to soak for 1.0h, heat and reflux for extraction for 1h, filter, and collect the filtrate. Add 6L of 75% ethanol to the dregs, extract for 2 hours; filter, and collect the filtrate; add 6 L of 95% ethanol to the dregs, extract for 1 h; filter, and collect the filtrate. Combine the filtrates for 3 times, recover the ethanol and concentrate it into a paste to obtain the ethanol extract A of Murata japonica.
[0046]b. Cool down the temperature of the ethanol extract A to below 0°C, then add ice water with ice cubes to the ethanol extract A, and grind continuously during the melting of the ice cubes to dissolve the ethanol extract A to form a suspension; control The temperature of the suspension is below 10°C, then extract and wash with petroleum ether, remove the components dissolved in petroleum ether, discard the petroleum ether extract, and the rest i...
Embodiment 3
[0049] a. Take 1kg of Gurixiang medicinal material, crush and sieve it, put it in an extraction container, add 10L of 60% ethanol to soak for 1.5h, heat and reflux to extract for 2.0h, filter, and collect the filtrate. Add 4L of 60% ethanol to the dregs, extract for 3 hours; filter and collect the filtrate; add 8 L of 60% ethanol to the dregs and extract for 1 h under reflux; filter and collect the filtrate. Combine the filtrates for 3 times, recover the ethanol and concentrate it into a paste to obtain the ethanol extract A of Murata japonica.
[0050] b. Cool down the temperature of the ethanol extract A to below 0°C, then add ice water with ice cubes to the ethanol extract A, and grind continuously during the melting of the ice cubes to dissolve the ethanol extract A to form a suspension; control The temperature of the suspension is below 10°C, then extract and wash with petroleum ether, remove the components dissolved in petroleum ether, discard the petroleum ether extract...
