Embodiment 1
[0022] Embodiment 1: prepare Rhizoma Chuanxiong extract: get 10 parts of Rhizoma Chuanxiong (part is: kilogram or gram)
[0023] Take Ligusticum chuanxiong, crush it into a coarse powder, soak it in 80% ethanol for 1 hour, then reflux extraction twice, add 8 times the amount of ethanol for the first time, extract for 2 hours, add 6 times the amount of ethanol for the second time, extract for 1.5 hours, and extract together After the extract was filtered and concentrated, it flowed through a macroporous adsorption resin column, washed with water, and then eluted with 30% ethanol. The 30% ethanol eluate was collected and concentrated under reduced pressure to obtain the Rhizoma Chuanxiong extract.
Embodiment 2
[0024] Embodiment 2: prepare Rhizoma Chuanxiong extract: 1000 parts of Rhizoma Chuanxiong (part is: kilogram or gram)
[0025] Take Ligusticum chuanxiong, crush it into a coarse powder, add water to extract 3 times, each time 10 times the amount of water, 1.5h, filter the extract, combine and concentrate the filtrate into a thick paste, add appropriate amount of water, heat to dissolve, add to the processed macropore Resin column (the ratio of dry paste and resin is 1:15-20), wash with water until the reaction of sugar is negative (1ml eluent, add 2-3 drops of 5% a-naphthol ethanol solution, shake well, Slowly add 0.5ml of concentrated sulfuric acid to the wall of the test tube, and a purple ring will form at the interface between the test solution and sulfuric acid) and elute with 30% ethanol until it is colorless, collect the eluate and recover it under reduced pressure, and dry it at low temperature (50°C) to obtain Ligusticum chuanxiong. Extract I, add 6 times the amount o...
Embodiment 3
[0026] Embodiment 3: prepare Rhizoma Chuanxiong extract: 3000 parts of Rhizoma Chuanxiong (part is: kilogram or gram)
[0027] Take Ligusticum chuanxiong, crush it into a coarse powder, extract with ethanol reflux, concentrate the extract under reduced pressure, let it cool, remove sugar and oil, remove residual ethanol in a water bath, heat water to dissolve, extract with ether after cooling, and extract the ether extract with hydrochloric acid. The acid solution was adjusted to pH 9-10 with saturated sodium carbonate, extracted with chloroform, and the chloroform was recovered under reduced pressure to obtain the chloroform extract. Dissolve the chloroform extract with hydrochloric acid, adjust the pH to about 10 with ammonia water, extract with chloroform, recover the chloroform under reduced pressure to obtain the Rhizoma Chuanxiong extract.
