Embodiment 1
[0023] Embodiments 1 to 3 are specific implementations of the effective fraction of fennel fennel and its preparation method and application of the present invention, wherein embodiment 1 is the best embodiment.
[0024] Example 1
[0025] The preparation method comprises the following steps: pulverize the fennel fennel, use an ethanol solution with a mass percentage concentration of 75% to 85% for ultrasonic extraction for 1 hour, and filter to obtain an ultrasonic extraction solution and filter residue, and add ethanol with a mass percentage concentration of 75% to 85% to the filter residue The solution was refluxed and extracted 3 times, each time for 0.5 hours, to obtain a refluxed extract, combined with the ultrasonic extract and the refluxed extract, concentrated and dried to obtain an extract; take the extract and disperse it with distilled water to obtain an extract dispersion, and sequentially use petroleum ether, acetic acid Ethyl ester and n-butanol are used as solv...
Embodiment 2
[0027] The preparation method comprises the following steps: pulverize the fennel fennel, use an ethanol solution with a mass percentage concentration of 85% to 95% for ultrasonic extraction for 3 hours, filter to obtain an ultrasonic extraction solution and filter residue, and add ethanol with a mass percentage concentration of 85% to 95% to the filter residue The solution was refluxed twice, each time for 1 hour, to obtain a reflux extract, combined with the ultrasonic extraction and reflux extract, concentrated and dried to obtain an extract; take the extract and disperse it with distilled water to obtain an extract dispersion, which was sequentially washed with petroleum ether, acetic acid Ethyl ester and n-butanol are used as solvents to extract the extract dispersion, and the obtained n-butanol extract is evaporated to obtain the n-butanol part of fennel fennel, and the extracted extract dispersion is concentrated and dried to obtain fennel fennel Aqueous phase extraction...
