Embodiment 1
[0085] ①Take the dried snow lotus, crush it, add 13 times the amount of ethanol solution with a volume concentration of 50%, warm soak and extract at 50°C, filter the extract, concentrate under reduced pressure to a specific gravity of about 1.40g / ml, and obtain the alcohol extract;
[0086] ② Disperse the extract with 3 times the amount of water to obtain a water dispersion system, sequentially extract 3 times with petroleum ether, ethyl acetate and n-butanol equivalent to 1 / 2 volume of the water dispersion system, and combine the petroleum ether, ethyl acetate and n-butanol after multiple extractions respectively. Ethyl acetate and n-butanol extracts were concentrated under reduced pressure and freeze-dried to obtain petroleum ether, ethyl acetate and n-butanol fractions respectively;
Embodiment 2
[0088] ①Use 13 times the amount of ethanol solution with a volume concentration of 0.01-95% to extract the dried and crushed snow lotus at 20-70°C, filter and concentrate to extract; ②Use 15 times the amount and the temperature is 60°C Dissolve the above-mentioned extract in hot water, cool and filter to remove the fat-soluble components to obtain the extract; ③ Slowly flow the extract through the macroporous resin column that has been eluted with ethanol; ④ Rinse the above-mentioned macroporous resin column with distilled water first , and then wash the macroporous resin column with an ethanol solution with a volume concentration of 80%, collect the ethanol eluate, concentrate under reduced pressure, and dry in vacuum to obtain Saussurea sauraceae extract.
[0089] The warm soaking extraction described in step ① can be repeated 3 times.
[0090] In step ③, after the extract flows through the polyamide column, the polyamide column is rinsed with distilled water, and the eluent...
