Attached Figure Description

[0018] Figure 1 This is a schematic diagram of the preparation process of the Tongli capsule of the present invention. Detailed Implementation

[0019] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] The Tongli Capsule of this invention comprises the following raw materials: ground beetle, prepared arisaema, vinegar-processed frankincense, vinegar-processed myrrh, dragon bone, angelica dahurica, safflower, safflower, notopterygium incisum, angelica sinensis, saposhnikovia divaricata, cimicifuga foetida, chuanxiong rhizome, and acorus tatarinowii, totaling fourteen Chinese medicinal herbs.

[0021] In a broad embodiment, the weight parts of the above-mentioned raw materials may be: 5-15 parts of ground beetle, 7-18 parts of processed arisaema, 20-35 parts of vinegar-processed frankincense, 15-24 parts of vinegar-processed myrrh, 13-121 parts of dragon bone, 22-37 parts of angelica dahurica, 15-20 parts of angelica sinensis, 22-31 parts of safflower, 21-36 parts of notopterygium incisum, 10-20 parts of angelica sinensis, 19-29 parts of saposhnikovia divaricata, 25-35 parts of cimicifuga foetida, 18-25 parts of chuanxiong rhizome, and 21-31 parts of acorus tatarinowii.

[0022] II. Preparation Process The preparation process of the Tongli capsule of the present invention includes the following steps: (1) Ingredients Weigh the following raw materials according to the prescription: Eupolyphaga sinensis, processed Arisaema heterophyllum, vinegar-processed frankincense, vinegar-processed myrrh, dragon bone, Angelica dahurica, Panax quinquefolius, safflower, Notopterygium incisum, Angelica sinensis, Saposhnikovia divaricata, Cimicifuga foetida, Ligusticum chuanxiong, and Acorus tatarinowii. All raw materials should be processed medicinal slices or herbs that meet the standards of the Pharmacopoeia.

[0023] (2) Mixing and grinding Mix all weighed raw materials thoroughly, then pulverize them. A mixed pulverization method can be used, where all the herbs are mixed and pulverized together to ensure uniform distribution of the components. The fineness of the pulverized material should meet the requirements for sieving.

[0024] In a preferred embodiment, the powder is pulverized and then passed through an 80-120 mesh sieve. More preferably, it is passed through a 100 mesh sieve to ensure uniform particle size, which is beneficial for subsequent mixing and filling, while ensuring the dissolution and bioavailability of the drug in vivo.

[0025] (3) Drying The pulverized powder is then dried to remove excess moisture, prevent mold growth, and extend shelf life. The drying temperature should be controlled within a suitable range to avoid damaging heat-sensitive components due to high temperatures.

[0026] In a general embodiment, the drying temperature is 50-70°C. In a preferred embodiment, the drying temperature is 60±2°C. This low-temperature drying condition can effectively protect the volatile components in the medicinal materials (such as the volatile oil in Saposhnikovia divaricata and ligustilide in Ligusticum chuanxiong) from loss due to high temperatures.

[0027] (4) Sieving The dried fine powder is sieved again to remove any lumps or agglomerates that may have formed during the drying process, ensuring the uniformity and flowability of the powder.

[0028] In a preferred embodiment, the sieve mesh size is 80-120 mesh, more preferably 100 mesh.

[0029] (5) Filling The sieved, uniform fine powder is then filled into the capsule shells. The filling process should be carried out in a clean environment to ensure compliance with Good Manufacturing Practices (GMP) requirements.

[0030] In a preferred embodiment, filling is performed using an automated capsule filling machine to ensure that the fill volume variation complies with pharmacopoeia requirements. After filling, the capsules undergo visual inspection and fill volume variation checks, and defective capsules are discarded.

[0031] (6) Packaging The filled capsules are then packaged into inner and outer packaging. Inner packaging typically uses pharmaceutical-grade PVC rigid sheets and aluminum foil blister packs, or pharmaceutical-grade plastic bottles; outer packaging uses cardboard boxes with labels affixed or printed, indicating information such as the drug name, specifications, batch number, production date, and expiration date.

[0032] III. Quality Control 1. Characteristics The Tongli capsules prepared according to the above process contain a brown powder with a bitter taste and a fragrant odor.

[0033] 2. Thin-layer chromatography identification The Tongli capsules of the present invention have at least one of the following thin-layer chromatographic identification characteristics: (a) Identification of windproof Take an appropriate amount of the contents of this product (e.g., 10g), add 20-30ml of methanol, sonicate for 15-30 minutes, filter, evaporate the filtrate to dryness, dissolve the residue in 1ml of methanol to obtain the test solution. Prepare a reference solution using the same method with a separate sample of *Saposhnikovia divaricata*. Perform thin-layer chromatography (General Chapter 0502 of the Chinese Pharmacopoeia). Apply 5-10μl each of the test solution and the reference solution to the same silica gel G thin-layer plate. Develop using petroleum ether (60-90℃)-ethyl acetate (17:1) as the developing solvent. Remove the plate, air dry, spray with 5% vanillin-sulfuric acid solution, and heat at 105℃ until the spots are clearly visible. The chromatogram of the test sample should show spots of the same color at the corresponding positions as the chromatogram of the reference sample.

[0034] (b) Identification of imperatorin and isoimperatorin Take an appropriate amount of the contents of this product (e.g., 10g), add 20ml of diethyl ether, soak for 30-60 minutes, sonicate for 5-10 minutes, filter, evaporate the filtrate to dryness, dissolve the residue in 1ml of ethyl acetate to obtain the test solution. Separately, prepare a mixed solution containing 1mg of each of imperatorin and isoimperatorin reference standards in ethyl acetate to obtain the reference solution. Perform thin-layer chromatography, applying 5μl of each of the above two solutions separately to the same silica gel G thin-layer plate. Develop the plate using petroleum ether (30-60℃)-diethyl ether (3:2) as the developing solvent. Remove the plate, air dry, and examine under ultraviolet light (365nm). The test sample chromatogram should show fluorescent spots of the same color at the corresponding positions as the reference chromatogram.

[0035] The above two identification features can be used alone or in combination to comprehensively control product quality. The identification of Saposhnikovia divaricata mainly targets the authenticity of the Saposhnikovia divaricata herb in the formula, while the identification of imperatorin and isoimperatorin mainly targets Angelica dahurica or related herbs that may be contained in the formula (Angelica dahurica contains coumarin components such as imperatorin and isoimperatorin).
