Embodiment 1
[0022] Embodiments 1 to 3 are specific implementations of the effective fraction of Corydalis nepalensis and the preparation method thereof of the present invention, wherein embodiment 1 is the best embodiment.
[0023] Example 1
[0024] The preparation method comprises the following steps: pulverize the whole plant of Corydalis nepalensis, use an ethanol solution with a volume percentage concentration of 75-85% for ultrasonic extraction for 1 hour, and then filter to obtain an ultrasonic extraction liquid and a filter residue, and add the filter residue into an ethanol solution with a volume percentage concentration of 75-85% for reflux Extract 3 times, each time for 0.5 hours, to obtain the reflux extract, combine the acoustic wave extract and reflux extract, concentrate and dry to obtain the extract; disperse the extract with distilled water to obtain the extract dispersion, and then use petroleum ether, ethyl acetate Ester and n-butanol are used as solvents to extract the...
Embodiment 2
[0026] The preparation method comprises the steps of: pulverizing the whole plant of Corydalis nepalensis, ultrasonically extracting it with an ethanol solution with a concentration of 85-95% by volume for 3 hours, and then filtering to obtain an ultrasonic extraction liquid and filter residue, adding the filter residue to an ethanol solution with a concentration of 85-95% by volume to reflux Extract 3 times, each time for 1 hour, to obtain the reflux extract, combine the acoustic wave extract and reflux extract, concentrate and dry to obtain the extract; add distilled water to disperse the extract to obtain the extract dispersion, and then use petroleum ether, ethyl acetate Ester and n-butanol are used as solvents to extract the extract dispersion, and the ethyl acetate extract and the n-butanol extract are respectively evaporated to remove the solvents to obtain the ethyl acetate part of Nepalese Corydalis; after the extract dispersion is extracted, the remaining liquid is con...
Embodiment 3
[0028] The preparation method comprises the following steps: pulverize the whole plant of Corydalis nepalensis, use an ethanol solution with a volume percentage concentration of 65-75% for ultrasonic extraction for 0.5 hours, and then filter to obtain an ultrasonic extraction solution and a filter residue, and add the filter residue into an ethanol solution with a volume percentage concentration of 65-75% for reflux Extract twice, each time for 2 hours, to obtain the reflux extract, combine the acoustic wave extract and the reflux extract, concentrate and dry to obtain the extract; add distilled water to disperse the extract to obtain the extract dispersion, and then use petroleum ether, ethyl acetate Ester and n-butanol are used as solvents to extract the extract dispersion, and the ethyl acetate extract and the n-butanol extract are respectively evaporated to remove the solvents to obtain the ethyl acetate part of Nepalese Corydalis; after the extract dispersion is extracted, ...
