Embodiment 1
[0034] The preparation of embodiment 1 component A extract
example 1
[0036] (1) Take 1.0kg of Aconitum aconitum and 10g of Ligusticum chuanxiong, grind to 10-200 mesh, mix well, and obtain the material;
[0037] (2) Spray an appropriate amount of ammonia water (about 15-20mL) into the material obtained in step (1), seal and infiltrate for 10-20 minutes, add absolute ethanol (about 3.0kg), and ultrasonically extract at room temperature for 30 minutes , the ultrasonic frequency is 30kHz, filters, and the filtrate is concentrated under reduced pressure and reclaims ethanol to obtain the crude extract (about 200g);
[0038] (3) adding mass fraction in the crude extract that step (2) obtains is that 1% hydrochloric acid adjusts pH to 2-5, then adds ammoniacal liquor and adjusts pH to 9-11, then extracts 3 times with chloroform, merges organic phase, subtracts Concentrate under reduced pressure to obtain a concentrate, and vacuum-dry at 50° C. for 12 hours to obtain an extract of component A (about 120 g, referred to as product A1, and the main compo...
example 2
[0040] (1) Take 1.0 kg of Aconitum aconitum and 5.0 kg of Rhizoma Chuanxiong, grind to 10-200 mesh, mix well, and obtain the material;
[0041] (2) Spray an appropriate amount of ammonia water (about 100mL) into the material obtained in step (1), seal and infiltrate for 20-30 minutes, add absolute ethanol (about 48kg), soak and extract at 60°C for 6 hours, filter , the filtrate was concentrated under reduced pressure and recovered ethanol to obtain the crude extract (about 240g);
[0042] (3) adding mass fraction to the crude extract obtained in step (2) is 3% hydrochloric acid to adjust the pH to 2-5, then add ammonia water to adjust the pH to 9-11, then extract 5 times with ethyl acetate, and combine the organic phases , concentrating under reduced pressure to get the concentrate, vacuum drying at room temperature for 24 hours to get component A extract (about 135g, referred to as product A2, the HPLC collection of illustrative plates of product A2 is basically consistent wi...
