Embodiment 1
[0040] Embodiment 1 of the present invention: preparation of pharmaceutical composition I
[0041] Take 5kg of whole herb of Erigeron breviscapine, crush it, add about 15 liters of 70% alcohol, subject to submerging the medicinal material and slightly higher, heat and reflux for 1 hour, pour out the liquid, continue to add an appropriate amount of 70% alcohol, repeat the same operation, and extract 3 times, the last time the dregs are filtered. Combine the filtrates, concentrate under reduced pressure at 40-60°C to a volume of about 5 liters, dilute the concentrated solution with water to 10 liters, filter, and remove the filter residue. The filtrate was adsorbed and partitioned on the pretreated AB-8 macroporous adsorption resin column, firstly eluted with 30 liters of water, and then eluted with 20 liters of 80% alcohol. Concentrate the 80% alcohol eluate to about 1 liter, adjust the pH value to about 7.0 with 10% sodium hydroxide solution, and spray dry to obtain brown yel...
Embodiment 2
[0044] Embodiment 2 of the present invention: preparation of pharmaceutical composition II
[0045] Take 5kg of whole herb of Erigeron breviscapine, crush it, add about 15 liters of 70% alcohol, whichever is submerged and slightly higher than the medicinal material; heat and reflux for 1 hour, pour out the liquid, continue to add an appropriate amount of 70% alcohol, repeat the same operation, and extract 3 times, the last time the dregs are filtered. Combine the filtrates, concentrate under reduced pressure at 40-60°C to a volume of about 5 liters, dilute the concentrated solution with water to 10 liters, extract and degrease with No. 120 gasoline, extract the water layer with ethyl acetate for 3-4 times, combine the ethyl acetate part, Concentrate under reduced pressure to remove ethyl acetate to obtain a brownish yellow powder C (that is, the extract of Erigeron breviscapine), with a yield of 138 g and a yield of 2.76% (based on the raw material of the whole herb of Erigero...
Embodiment 3
[0048] Embodiment 3 of the present invention: the application of pharmaceutical composition I
[0049] Preparation of pharmaceutical tablets: take pharmaceutical composition I 100g, starch 50g, 10% starch slurry 10g and magnesium stearate 2g; after mixing pharmaceutical composition I and starch, add 10% starch slurry to make soft material , passed through a 14-mesh sieve to granulate, dried at a temperature of 70-80°C, passed through a 12-mesh sieve for granulation, mixed with magnesium stearate, pressed into 1000 tablets, and obtained. Each tablet contains medicinal composition I100mg, which can be used for treating or preventing diabetes.
