Embodiment 1
[0014] Embodiment 1, the preparation of breviscapine arginine double salt
[0015] Weigh 230 mg of breviscapine, completely dissolve it in 60 ml of absolute ethanol at a slight temperature, feed in portions under stirring, and add 116.0 mg of L-arginine. Let it cool down slightly, add sodium carbonate solution dropwise under stirring, and monitor the pH change until the pH is about 7-9. Continue to stir and reflux for 3 to 4 hours. After the reaction is completed, the reaction solvent is removed by rotary evaporation. After the residue is vacuum-dried for 2 hours, add 60ml to 100ml of ethanol, shake fully, filter under reduced pressure, and recover ethanol from the filtrate under reduced pressure. Place, filter with suction, and combine the filtrates. The filtrate was ultrasonically treated for 15-30 minutes, and then filtered with a 0.22 μm microporous membrane, and the filtrate was distilled to volume to obtain the final product. Or freeze-dry the filtrate to obtain white...
Embodiment 2
[0016] Example 2, Preparation of Breviscapine Lysine Double Saline Injection
[0017] Weigh 150 g of breviscapine lysine double salt, add 20,000 ml of purified water for injection, dissolve, filter, prepare 2 ml / bottle, and sterilize to obtain 10,000 water injections. Each bottle contains breviscapine lysine double salt 15mg.
Embodiment 3
[0018] Embodiment 3, preparation of breviscapine lysine powder injection
[0019] Weigh 200g of breviscapine lysine double salt, dextran S 40 160g, add 25000ml of water for injection to dissolve, filter through a 0.22μm microporous membrane, measure the content, and pack into 2.5ml each. Freeze-dry to obtain 10,000 breviscapine lysine double salt powder injections, each containing 20 mg breviscapine lysine double salt.
