[0029] The present invention also provides a preparation method of the compound shown in formula (I), comprising:
[0030] 1) extracting plants of the genus Epimedium to obtain a clear ointment;
[0031] 2) The obtained clear cream is separated to obtain the compound shown in formula (I).
[0032] According to the present invention, the present invention extracts plants of the genus Epimedium to obtain clear ointment; the plant of the genus Epimedium is preferably Epimedium, and in the extraction of the present invention, leaves of Epimedium are preferably used; The invention has no special limitation on the extraction method, any method known in the art for solvent extraction of Chinese herbal medicine components can be used, and the present invention preferably adopts the water alcohol precipitation method or alcohol extraction;
[0033] Specifically, in the present invention, plants of the genus Epimedium are crushed and sieved, mixed with water, extracted, the extract is ...
Embodiment 1
[0060] 1) 3.5kg of dried Epimedium leaves, pulverized and sieved, added 20 times the amount of water, extracted 3 times, each time for 1.5h, filtered, combined filtrates, concentrated under reduced pressure to obtain a clear cream; add ethanol to the clear cream to make the The amount of alcohol reaches 70wt%, standing at room temperature, filtering and concentrating, and recovering ethanol to obtain alcohol precipitation paste;
[0061] 2) Take the alcohol precipitation clear paste from step 1) and add purified water to dissolve it, let it stand at room temperature, take the supernatant and separate it through a D101 macroporous adsorption resin column, elute with 4 times the column volume of purified water, and discard the eluent , and then eluted with the same volume of 85% ethanol, and the 85% ethanol eluted part was collected; the 85% ethanol eluted part was passed through a D101 macroporous resin column, and gradient elution was carried out with different concentrations o...
