Embodiment 1
[0031] Example 1: Extracting breviscapine and dicaffeoylquinic acid from breviscapine
[0032] Take 50kg of whole scutellaria breviscapus, grind it into fine powder and extract with 95% ethanol, recover the ethanol to dry the extract, add water to suspend, extract with ethyl acetate and divide it into upper and lower layers, the upper layer is ethyl acetate, and the lower layer is water layer. The aqueous layer liquid was adjusted to pH 9 with 20% NaOH and left overnight, filtered to remove the precipitate, and the filtrate was adjusted to pH 6 with HCl to obtain the precipitate. The precipitate was dissolved in methanol, recrystallized in chloroform, and dried to obtain scutellarin, weighing 32 g.
Embodiment 2
[0033] The ethyl acetate layer was concentrated and passed through a polyamide column, eluted with dilute ethanol, tracked by TLC, collected the part with an Rf value of 0.5, concentrated to obtain the dicaffeoylquinic acid part, and weighed 46g after drying. Embodiment 2: the preparation of powder injection. Weigh 10g of breviscapine and 10g of dicaffeoylquinic acid, dissolve them with an appropriate amount of water for injection, add 1000ml-5000ml of water for injection, and add 30-40g of mannitol at 30°C to adjust the pH to 8.5, and the solution After sterile filtration, the filtrate was divided into 1000 5ml vials, freeze-dried, and capped to obtain the powder injection of the composition.
Embodiment 3
[0034] Example 3: Tablet preparation. Weigh 20g of breviscapine, 2g of dicaffeoylquinic acid, 40g of starch, and 3g of dextrin, mix well, add 10% starch slurry to make soft material, pass through a 14-mesh nylon sieve, ventilate and dry at 60-70°C, and sieve through a 16-mesh sieve granules, add 1.0g of magnesium stearate and 3g of sodium carboxymethyl starch, mix evenly, press into 1000 tablets, and coat them.
