Embodiment 1
[0059] A preparation method of Siwutang formula granules, comprising the steps of:
[0060] a. Take Rehmannia glutinosa 550g, Angelica sinensis 550g, Baishao 550g, Chuanxiong 550g, add 17.6kg of water, decoct and extract for 1 hour, that is, decoct once; after decocting, add 13.2kg of water to the dregs, decoct and extract for 1 hour, That is, the second decoction; during the two decoction extraction process, the aromatic water is collected;
[0061] b. Combine the two decoction filtrates, filter, and concentrate the filtrate under reduced pressure under vacuum to a concentrated solution with a relative density of 1.06 at 60°C;
[0062] c. Take the above concentrated solution and add β-cyclodextrin and silicon dioxide (bulk density is 0.15g / ml). The amount accounts for 0.8% of the weight of the solid content of the concentrated solution, and the clear paste is obtained after stirring evenly;
[0063] d. Mix the aromatic water and clear paste, then spray dry, control the air ...
Embodiment 2
[0067] A preparation method of Siwutang formula granules, comprising the steps of:
[0068] a. Take rehmannia glutinosa 1000g, angelica 900g, white peony root 800g, chuanxiong 800g, add 28.0kg of water, decoct and extract for 1.5 hours, that is, first fry; after the first decoction, add 21.0kg of water to the dregs, decoct and extract for 1 hour, That is, the second decoction; during the two decoction extraction process, the aromatic water is collected;
[0069] b. Combine the two decoction filtrates, filter, and concentrate the filtrate under reduced pressure under vacuum to a concentrated solution with a relative density of 1.07 at 60°C;
[0070] c. Take the above concentrated solution and add β-cyclodextrin and silicon dioxide (bulk density is 0.20g / ml). The amount accounts for 0.8% of the weight of the solid content of the concentrated solution, and the clear paste is obtained after stirring evenly;
[0071] d. Mix the aromatic water and clear paste, then spray dry, cont...
Embodiment 3
[0075] A preparation method of Siwutang formula granules, comprising the steps of:
[0076] a. Take 250g of rehmannia glutinosa, 250g of angelica, 200g of white peony root, 200g of Chuanxiong, add 9.0kg of water, decoct and extract for 1 hour, that is, first fry; after the first decoction, add 7.2kg of water to the dregs, decoct and extract for 1 hour, That is, the second decoction; during the two decoction extraction process, the aromatic water is collected;
[0077] b. Combine the two decoction filtrates, filter, and concentrate the filtrate under reduced pressure under vacuum to a concentrated solution with a relative density of 1.05 at 60°C;
[0078] c. Take the above concentrated solution and add β-cyclodextrin and silicon dioxide (bulk density is 0.18g / ml). The amount accounts for 0.5% of the weight of the solid content of the concentrated solution, and the clear paste is obtained after stirring evenly;
[0079] d. Mix the aromatic water and clear paste, then spray dry...
