Embodiment 1
[0043] The extraction method of serratine, it comprises the following steps:
[0044] 1) the white crane vine is ground into powder, add ethanol solvent, adopt cold dipping method to extract, evaporate ethanol solvent, obtain the first extract;
[0045] 2) The first extract is mixed with water to form a suspension, and petroleum ether, ethyl acetate and n-butanol are successively added to the suspension for extraction, the n-butanol extract is collected, and after concentrating, the second extract is obtained. paste;
[0046] 3) Take the second extract, carry out macroporous resin column chromatographic separation, use water-ethanol mixed solution as eluent, carry out gradient elution, and collect the eluate whose mass fraction of ethanol is 40% to 70% , the eluate is concentrated to obtain the third extract;
[0047] 4) The third extract is recrystallized from methanol to obtain the cymenine.
Embodiment 2
[0049] The extraction method of serratine, it comprises the following steps:
[0050] 1) Grinding the white crane vine into powder, adding a volume fraction of 75% ethanol solvent of 15 times the weight of the white crane vine coarse powder, soaking at 0° C. for 24 hours to extract the white crane vine, evaporating the ethanol solvent to obtain the first extract;
