[0049] A preparation method of embedding liquid includes the following steps:
[0050] S1. Use honeysuckle and angelica to add water to obtain aromatic water a through steam distillation;
[0051] S2, mixing the remaining medicine residue after filtering in step S1 with rhubarb and ebony, adding water, and cooking;
[0052] S3. Filtrate with a screen to obtain filtrate b and medicine residue, and cook the medicine residue with water; after cooking, filter with a screen to obtain filtrate c;
[0053] S4. Combine filtrate b and filtrate c to obtain a total filtrate, which is precipitated with absolute ethanol and filtered through a sieve; obtaining the final filtrate c;
[0054] S5. Under stirring, slowly add aromatic water a to the final filtrate c to obtain the traditional Chinese medicine extract X, and store it in an environment of 5℃±2℃ for later use;
[0055] S6. Mix hydroxyethyl fiber and polyvinylpyrrolidone, dissolve in water, and stir to react under high pressure and temperature ...
Embodiment A
[0146] S1. Use honeysuckle and angelica to add 9 times the mixed amount of water to obtain aromatic water a by steam distillation; the addition of honeysuckle and angelica is shown in Table 1;
[0147] S2. Mix the remaining medicinal residues after filtering in step S1 with rhubarb and ebony plum and add 9 times the mixed amount of water, and cook for 60 minutes. The addition of rhubarb and ebony plum is shown in Table 1;
[0148] S3. Filtrate with a 300-mesh screen to obtain filtrate b and drug residue, and cook the drug residue with 5 times the mixed amount of water for 30 minutes; filter with a 300-mesh screen to obtain filtrate c;
[0149] S4. Combine filtrate b and filtrate c to obtain a total filtrate, which is precipitated with 60% absolute ethanol and filtered through a 300-mesh sieve; obtaining the final filtrate c;
[0150] S5. Stir at 300 rpm, slowly add aromatic water a to the final filtrate c to obtain the Chinese medicine extract X, and store it in an environment of 5℃±2℃...
Embodiment B1
[0171] Steps S1-S5, there is no need to use Chinese medicine extract X, so it is omitted and not done;
[0172] S6. Take 0.15% of 100,000-viscosity hydroxyethyl fiber and 0.35% of polyvinylpyrrolidone K30, dissolve in water, maintain 10Mpa, and maintain 12000 revolutions / min at 120°C for 3 minutes;
[0173] S7. Control the reaction temperature of hydroxyethyl fiber and polyvinylpyrrolidone K30 at 40°C, and make the dispersion into a uniform state;
[0174] S8. Take 25% distilled water into the dispersion of step S7, stir at 3000 rpm, pressure 10Mpa, temperature at 40°C, invert once every 5 minutes, and continue stirring for 30 minutes;
[0175] S9. After the stirring is stopped, cool to a probe temperature of 5°C, and keep it sealed in a 10Mpa environment for 1 hour; to obtain the embedding liquid of Example B1;
[0176] S10. Take 20% glycerin and 0.2% carbomer and mix with water, keep 12Mpa, and use stirring speed of 15000 rpm and temperature of 120℃ to keep homogeneous dispersion for ...
