Examples
Embodiment 1
[0037] Embodiment 1 percolation method extracts rose
[0038] Crush 1-2kg of roses into coarse powder, add 8-15 times of 30%-90% ethanol, collect percolation liquid at a speed of 1-3ml / min to extract active ingredients, recover ethanol under reduced pressure, concentrate to Thick paste, that is, the relative density is between 1.13-1.28. Add water to dissolve the extract, add 2-5 times of n-butanol to extract, repeat 2-3 times, so that the total flavonoids of roses account for more than 40% of the extract (calculated as dry product).
Embodiment 2
[0039] Embodiment 2 reflux method extracts rose
[0040] Crush 1-2kg of roses into coarse powder, add 8-15 times the mass of 30%-90% ethanol to soak for 2-4h, make up the amount of water according to the water absorption rate before reflux, reflux for 1-2h for the first time, and reflux for the second time For the third time, add 8 times the amount of ethanol to reflux for 0.5-1h, filter, recover ethanol under reduced pressure, concentrate to a thick paste, that is, the relative density is between 1.13-1.28. Add water to dissolve the extract, add 2-5 times of n-butanol to extract, repeat 2-3 times, so that the total flavonoids of roses account for more than 60% of the extract.
Embodiment 3
[0041] Embodiment 3 Ultrasonic method extracts rose
[0042] Crush 1-2kg of roses into coarse powder, add 8-15 times of 30%-90% ethanol to soak for 2-4h, make up the amount of water according to the water absorption rate before ultrasonication, first ultrasonication for 10-40min, second, For the third time, add 8 times the amount of ethanol and sonicate for 0.5h, filter, combine the three filtrates, recover ethanol under reduced pressure, concentrate to a thick paste, that is, the relative density is between 1.13-1.28. Add water to dissolve the extract, add 2-5 times of n-butanol to extract, repeat 2-3 times, so that the total flavonoids of roses account for more than 60% of the extract.
