Problems solved by technology

Studies have shown that compared with other oral preparations, pellet preparations have many advantages, such as improving the bioavailability of drugs, good absorption reproducibility, easy to achieve the expected drug release rate, achieving ideal blood drug concentrations, and avoiding drug exposure. The hazards caused by sudden release, etc., but the preparation process of my country's pellets has disadvantages such as backward technology, high work intensity, and low efficiency.
Patents 200510200475 and 200610059817 have made some improvements to the preparation of cassia twigs and poria pellets, but in the above-mentioned patent materials, cassia twigs use alcohol or water to extract active ingredients, and cassia twigs mainly contain volatile oil, in which cinnamic aldehyde and cinnamic acid content Higher, cinnamon aldehyde, cinnamon oil all have significant activity of inhibiting platelet aggregation, have analgesic effect etc., if use above-mentioned method, the active pharmaceutical ingredient in cassia twig will inevitably be lost, thereby reduce drug effect
Moreover, the spheronization-extrusion method is generally used to prepare micropills in China, and there is no literature on the preparation of micropills by using cinnamon twig and poria extract powder and extract

Embodiment 1

[0038] Take 700g of Guizhi, 700g of Poria, 700g of Cortex Moutan, 700g of Radix Paeoniae Rubra, and 700g of peach kernel for later use.

[0039] The preparation method is:

[0040] 1. Grind Poria cocos into fine powder for later use;

[0041] 2. Add the cassia twig to 7 times the mass of water, soak for 1-2 hours, extract the volatile oil with a volatile oil extractor for 4-5 hours, save the volatile oil after extraction, and separate the liquid medicine and dregs for later use;

[0042] 3. Crush the bark of Moutan, add 20 times the mass of water and soak for 1-2 hours, then collect the distillate of 10 times the mass of the bark of Moutan by steam distillation, refrigerate the distillate to precipitate crystals, filter and store the crystals, and add 5 wt% of the filtrate to the filtrate Continue to distill and extract the sodium chloride, collect the distillate that is 3-5 times the mass of Moutan Cortex, and refrigerate the distillate again to precipitate crystals. After f...

Embodiment 2

[0053] The preparation method is the same as in Example 1, the difference is that in step 2, cinnamon twigs are added to 6 mass times of water; in step 3, Moutan cortex is soaked in 25 mass times of water, and then 15 times of the distillate is collected; the final obtained pellet pine The density is 89.2g / 100cm 3 , the angle of repose is 21.7°

Embodiment 3

[0055] The preparation method is the same as that in Example 1, except that in step 4, 10 mass times of water is added for decocting each time; in step 5, alcohol is added until the alcohol content is 50% by volume; in step 6, 6 mass times of the mixture is added beta-cyclodextrin. The bulk density of the final gained pellets is 88.5g / 100cm 3 , the angle of repose is 21.9°

Abstract

The invention discloses a preparation method of micro-pills prepared from cassia twig and tuckahoe, which comprises the following steps: extracting volatile components from cassia twig and moutan bark; mixing the dregs of the cassia twig and moutan bark with red peony root and peach kernels, boiling with water, merging the obtained decoction and the liquid medicine of the cassia twig and moutan bark after the volatile components are extracted, concentrating, depositing in alcohol, filtering, and taking the filtered solution; carrying out inclusion on the volatile components of the cassia twigand moutan bark to obtain inclusion complexes; and respectively preparing a powdered extract, an extract and a fluid extract by using the filtered solution, fine tuckahoe powder and the inclusion complexes, preparing female mold pills by using the powdered extract as a mold core and using the extract as a bonding agent, preparing micro-pills by using the fluid extract as a spouting increasing agent and using a fluidized bed granulation method, and coating to obtain the micro-pills prepared from cassia twig and tuckahoe. By the invention, the effective components of the medicines are effectively extracted, the medical effect is improved, and the performance quality of products is stable. By using the pure powdered extract prepared from cassia twig and tuckahoe as the mold core, the medicine carrying content of the micro-pills is high; by using the fluidized bed granulation method for preparing the micro-pills, the yield is high; and after the micro-pills are coated, the hygroscopicity of the micro-pills is obviously reduced, thereby solving the problem of moisture absorption of a pure extract preparation.

Description

technical field [0001] The invention relates to a preparation method of cinnamon twigs and poria preparations, in particular to a preparation method of cinnamon twigs and poria pellets, and belongs to the technical field of pharmacy. Background technique [0002] Guizhi Fuling Pills is published in the chapter "Golden Relics: Syndrome and Syndrome of Women's Pregnancy". Zhang Zhongjing used it to treat women's post-pregnancy leaks and restless fetal movement because of its function of promoting blood circulation and removing traces, eliminating symptoms and accumulation. In the prescription, Guizhi is used as the main medicine, warming the blood vessels; peach kernel and paeonol, promoting blood circulation and removing blood stasis; red peony root, softening the liver and restraining yin, harmonizing the camp and health; Poria cocos, invigorating the spleen and nourishing the middle, promoting dampness and helping Gui to pass through. In recent years, a large number of expe...
