[0051] Preferably,

[0052] The preparation method of the present invention is as follows:

[0053] (a) Accurately weigh various raw materials required for the formula, crush and grind them through a crushing device, and screen them through a 90-mesh sieve to obtain fine powder;

[0054] (b) Soak the above-mentioned medicinal materials with a four-component extraction solvent ethanol-pure water-choline chloride-glycerol, with a molar ratio of 3:1:1:2, for 60 minutes;

[0055] (c) Adopt microwave-assisted extraction technology to extract the active ingredients of traditional Chinese medicine, set the microwave power to 550W, the volume ratio of material to liquid to 1:9, extract in 3 cycles, with a single extraction time of 5 minutes; The core differential parameters include: accurately controlling the temperature at 45°C, with a fluctuation range of ±0.5°C, and adopting a quaternary composite solvent system ethanol-pure water-choline chloride-glycerol, with a molar ratio of 3:1:1:2, in which the deep eutectic solvent DES is pre-synthesized from choline chloride and glycerol at a molar ratio of 1:2 and then introduced into the system;

[0056] (d) Perform solid-liquid separation operation to obtain filtrate;

[0057] (e) Adopt thin-film evaporation concentration technology to concentrate the filtrate, select a centrifugal thin-film evaporation device, and accurately control the feeding rate of the medicinal liquid through a flow regulating valve; After the medicinal liquid enters the evaporation device, an ultra-thin liquid film of 0.03 mm is formed under the action of centrifugal force, the solvent is instantaneously vaporized, and the vaporization product passes through a rotary vapor-liquid separation system, and the solvent vapor and high-concentration concentrated liquid are efficiently separated relying on a centrifugal force field of 255 rpm; The core differential process parameters include: controlling the heating time, the optimal residence time of the material on the heating surface is 21 seconds, which corresponds to a centrifugal force field of 255 rpm at this time, and the stability of heat-sensitive components is ensured through the dynamic matching of the centrifugal speed and the liquid film thickness; Gradient temperature control strategy: In the double-effect temperature gradient configuration, the high-temperature zone of the first effect maintains 60°C to accelerate the phase change process, and the low-temperature zone of the second effect maintains 56°C, based on the actual measured value of the boiling point of the filtrate at 50°C under a vacuum of -0.08 MPa, and the evaporation driving force ΔT = 6°C;

[0058] (f) Homogenize and mix the concentrated solution with excipients xylitol and dextrin to prepare an external cream.

[0059] (g) Implement a low-temperature dehydration process by freeze-drying to prepare a lyophilized powder preparation; the core differential process parameters include: setting the pre-freezing temperature to -33°C. Based on the actual measurement by differential scanning calorimetry (DSC), the eutectic point temperature of this system is -25°C, and the pre-freezing temperature is 8°C lower than the eutectic point to ensure complete freezing; controlling the primary drying temperature, i.e., the sublimation temperature, to -21°C. According to DSC, the disintegration temperature Tc of the system is -16°C, and the primary drying temperature is 5°C lower than Tc to maintain the stability of the porous framework structure; setting the secondary drying temperature, i.e., the desorption temperature, to 37°C, and promoting the desorption of bound water by gradient heating to optimize the moisture content of the final product.

[0060] (h) Using the lyophilized powder as the raw material, achieve multi-form transformation through the following formulation process paths: Tablet preparation process, compound the lyophilized powder with binder hydroxypropyl methylcellulose (HPMC) and disintegrant microcrystalline cellulose (MCC), and make tablets through direct compression. HPMC enhances the adhesion between particles through a hydrogen bond network, and MCC promotes disintegration through capillary action. The optimal ratio of lyophilized powder:HPMC:MCC by mass is 12:2:3; Capsule preparation process, mix and homogenize the lyophilized powder with lubricant magnesium stearate, and after optimizing the fluidity, fill it into hard capsule shells. Magnesium stearate reduces the friction coefficient between particles through a hydrophobic film, and the optimal addition amount of magnesium stearate is 1.0% w / w; Granule preparation process, adopt the wet granulation process, screen the granules through a 20-mesh sieve after wet granulation, and obtain granules after drying.

[0061] Preferably,

[0062] In step (a), the screening mesh number is 90 meshes.

[0063] In step (b), the soaking solution is a four-component solvent of ethanol - pure water - choline chloride - glycerol, and its molar ratio is 3:1:1:2.

[0064] In step (c), the extraction temperature is 45°C, and the extraction solvent is a four-component solvent of ethanol - pure water - choline chloride - glycerol, and its molar ratio is 3:1:1:2.

[0065] In step (e), the optimal residence time of the material on the heating surface is 21 seconds, the corresponding centrifugal speed is 255 rpm, the high-temperature zone of the first effect is 60°C, and the low-temperature zone of the second effect is 56°C.

[0066] In step (g), the pre-freezing temperature is -33°C, the primary drying temperature is -21°C, and the secondary drying temperature is 37°C; in step (h), the mass ratio of lyophilized powder:HPMC:MCC is 12:2:3.

[0067] The present invention can also be made into a decoction: Weigh Sophora flavescens, Magnolia officinalis, wax gourd peel, plantain herb, Trachelospermum jasminoides according to the prescription; soak them in 10 - 12 times the amount of water for 50 minutes, bring to a boil over high heat and then turn to low heat and decoct for 25 minutes, add Herba Euphorbiae Humifusae, Gentiana macrophylla, Poria cocos, Siegesbeckia orientalis, processed Polygonum multiflorum according to the prescription amount, continue to decoct over low heat for 35 minutes, add Viola philippica according to the prescription amount, continue to decoct over low heat for 35 minutes, filter while it is hot, add water to the medicinal residues (half of the first added water amount) and decoct again for 40 minutes, combine the two decoctions and take them warm in 3 divided doses.

[0068] The preparation forms of the present invention have the characteristics of diversification. It not only supports the external-use ointment dosage form, but also can be prepared into internal-use oral solid preparations (such as tablets, capsules, granules) or liquid preparations (such as decoctions). The administration routes and dosage form selections are flexible. Specifically, its external application preparation can be administered through skin penetration, while the internal use preparations cover conventional dosage forms such as powders, tablets, capsules, etc., and can also be in the form of traditional decoctions according to clinical needs, fully reflecting the multi-route application advantages of traditional Chinese medicine compound preparations.

[0069] The microwave-assisted extraction technology is an innovative method for the efficient separation of active ingredients from traditional Chinese medicine based on the selective thermal effect of microwave radiation on polar molecules and the deep penetration of electromagnetic waves. Its core mechanisms include molecular polarization induced by the electromagnetic field and the change of cell membrane permeability, and significantly improve the mass transfer efficiency through the mechanism of synchronous heating of the whole material. For example, the extraction time of ginkgo flavonoids is shortened to 1 / 8 of the traditional reflux method (only 8 minutes). This technology, through the principle of directional energy transfer, preferentially activates active ingredients containing polar functional groups (such as the hydrogen bond network of polysaccharide - water molecules), and the extraction rate of flavonoids such as quercetin is increased by 38 times compared with Soxhlet extraction. After optimizing the solvent system, using deep eutectic solvents (such as choline - lactic acid system) can reduce the solvent consumption by 60% - 85%. For example, when extracting rosmarinic acid with an ethanol - water mixed solvent, the dosage is reduced by 78%. The unique non-thermal effect (such as ion migration inducing cell wall rupture) combined with precise temperature control (40 - 60 °C) enables the biological activity retention rate of heat-sensitive substances such as perillaldehyde substances to exceed 95%. Typical applications include: extracting citrus pectin only takes 12 minutes (the traditional acid hydrolysis method takes 2 hours), and the molecular weight distribution is more uniform; the mass transfer rate of the polyphenol - propylene glycol composite system in the microwave field is increased by 16 times, fully reflecting the unique advantages of this technology in the green manufacturing of modern traditional Chinese medicine preparations.

[0070] Thin-film evaporation technology has demonstrated significant value in process innovation in the field of traditional Chinese medicine concentration. Through the synergistic effect of mechanical film formation and vacuum environment, it realizes the efficient, energy-saving and low-temperature treatment of liquid medicine. This technology uses a rotating scraper or a precision distributor to form a micron-level thin film of the liquid medicine on the heat transfer interface. Through an efficient mass transfer and vaporization separation mechanism, evaporation and concentration can be completed within the temperature range of 40-60°C, and the heat exposure time is shortened by more than 80% compared with the traditional evaporation process. Such mild operating conditions effectively avoid the decomposition risk of heat-sensitive components, and the biological activity retention rate can reach more than 95%. The industrial-grade thin-film evaporation system adopts a modular design, and the daily processing capacity of a single unit breaks through the 5-ton scale. Through gradient vacuum control and energy recycling technology, the unit energy consumption is reduced by 40%-60% compared with traditional rotary evaporation equipment. Its core advantages are reflected in: 1) By using dynamic film formation technology, the liquid film thickness is controlled within the range of 0.1-0.5 mm, and the heat transfer coefficient is increased to 3-5 times that of traditional evaporators; 2) The vacuum operating environment reduces the boiling point of the solvent by 30-50°C, realizing low-temperature and rapid phase change; 3) The intelligent control system precisely adjusts the scraping film speed (15-300 rpm) and evaporation pressure (5-500 mbar) to ensure the stable processing of liquid medicines with different viscosities.

[0071] Freeze-drying technology has the following core advantages:

[0072] First, the high retention characteristics of active ingredients. The low-temperature and negative-pressure environment blocks the decomposition of heat-sensitive substances (such as enzyme preparations, volatile oils, alkaloids), and the active ingredient retention rates of astragaloside IV and notoginsenoside are ≥95%. The low volatility and dissipation characteristics, and the vacuum phase change mechanism make the loss rate of volatile substances (such as borneol, zedoary oil) less than 15% of the traditional process. The environmental control advantage is that the operating parameters (temperature ≤ -40°C, vacuum degree ≤ 10 Pa) effectively inhibit the activity of oxidase and the proliferation of microorganisms, and the total number of colonies of the product is reduced by 2 orders of magnitude compared with the conventional process.

[0073] Second, the characteristics of microstructure reconstruction. The directional sublimation of ice crystals forms a three-dimensional microporous network, and the integrity of plant cells reaches 97% ± 2%. After rehydration, the morphological recovery rate is ≥90%. Typical products such as freeze-dried dendrobium slices have a similarity of 92% in vascular bundle structure with fresh products, and the microscopic characteristics are completely retained. The porous structure characteristics make the specific surface area of freeze-dried powder reach 50-200 m 2 / g, and the reconstitution time is shortened to 1 / 3 of that of traditional products.

[0074] Third, the advantage of improved stability. The moisture content of the final product is controlled ≤ 3% (8-12% for traditional hot air drying). For example, the moisture content of freeze-dried red ginseng is 1.5 ± 0.3%, and the shelf life at room temperature is extended to 36-60 months. The volume compression ratio reaches 5:1, reducing the storage and transportation costs by more than 40%.

[0075] Fourth, the mechanism for enhanced bioavailability. The cell wall breaking rate reaches 98.5 ± 1.2%, the dissolution rate of active ingredients (such as ursolic acid and tanshinone) is increased by 3.2 times, and the peak blood drug concentration is increased by 40 - 60%. The process parameters are intelligently controlled (temperature fluctuation ± 0.5°C, vacuum deviation ≤ 2%), and the RSD of ingredient content between batches is < 3%.

[0076] Fifth, the dual benefits of safety and environmental protection. No chemical preservatives are added, and the solvent residue in the freeze-drying process is < 10 ppm. The energy recycling system reduces the unit energy consumption by 35 - 55%, and the carbon footprint is reduced by 45% ± 5% compared with the traditional process.

[0077] In the preparation steps of this formulation system, during the microwave-assisted extraction process, through process optimization, the extraction temperature is optimized to 45°C. A temperature one degree higher or lower will seriously affect the extraction efficiency, which is the temperature corresponding to the four-component extraction solvent. The extraction solvent is the four-component solvent "ethanol - pure water - choline chloride - glycerol" (molar ratio 3:1:1:2). Compared with the traditional extraction solvent, it greatly improves the extraction efficiency while ensuring dosage safety and also significantly reduces the residual amount of active ingredients.

[0078] In the preparation steps of this formulation system, during the thin-film evaporation and concentration process, through process optimization, the residence time of the material on the heating surface is optimized to 21 seconds. At this time, the corresponding centrifugal speed is 255 rpm, the high-temperature zone of the first effect is 60°C, and the low-temperature zone of the second effect is 56°C. The following key system parameters are obtained: the temperature of the low-temperature zone of the second effect is 6°C higher than the boiling point of the filtrate at high vacuum.

[0079] In the preparation steps of this formulation system, during the freeze-drying process, through process optimization, the pre-freezing temperature is optimized to -33°C, the sublimation temperature (primary drying temperature) is -21°C, and the desorption temperature (secondary drying temperature) is 37°C. Using differential scanning calorimetry (DSC), the eutectic point temperature is measured to be -25°C, and the following key parameter of this system is obtained: the pre-freezing temperature is 8°C lower than the eutectic point of the material. Using differential scanning calorimetry (DSC), the collapse temperature is measured to be -16°C, and the following key parameter of this system is obtained: the sublimation temperature is 5°C lower than the collapse temperature.

Based on the actual measurement by differential scanning calorimetry (DSC), the eutectic point temperature of this system is -25°C, and the pre-freezing temperature is 8°C lower than the eutectic point to ensure complete freezing; the control of the primary drying temperature, that is, the sublimation temperature, is controlled to -21°C. According to DSC, the disintegration temperature Tc of the system is -16°C, and the primary drying temperature is 5°C lower than Tc to maintain the stability of the porous skeleton structure; the setting of the secondary drying temperature, that is, the desorption temperature, is set to 37°C. By gradient heating, the desorption of bound water is promoted to optimize the moisture content of the final product;

[0107] (h) Using the freeze-dried powder as the raw material, multi-dose form conversion is achieved through the following pharmaceutical preparation process routes: Tablet preparation process: The freeze-dried powder is compounded with the binder hydroxypropyl methylcellulose (HPMC) and the disintegrant microcrystalline cellulose (MCC), and tablets are made through the direct compression process. HPMC enhances the adhesion force between particles through the hydrogen bond network, and MCC promotes disintegration through capillary action. The optimal ratio of freeze-dried powder:HPMC:MCC by mass is 12:2:3; Capsule preparation process: The freeze-dried powder is mixed and homogenized with the lubricant magnesium stearate, and after optimizing the fluidity, it is filled into hard capsule shells. Magnesium stearate reduces the friction coefficient between particles through a hydrophobic film, and the optimal addition amount of magnesium stearate is 1.0% w / w; Granule preparation process: The wet granulation process is adopted, and after wet granulation, it is sized through a 20-mesh sieve and dried to obtain granules.
