Embodiment 1
[0035] The tablet preparation of embodiment 1 medicine of the present invention
[0036] Mix the full prescription amount of Pulsatilla chinensis, the full prescription amount of Jiaobaizhu, and the half prescription amount of other medicinal flavors in the prescription medicinal materials, and ultrafinely pulverize it until the particle size reaches below 100nm to obtain the nano powder original drug.
[0037]Decoct the half-prescription amount of other medicinal herbs except Pulsatilla Pulsatillae and Jiaobaizhu in water for 1 hour, filter out the medicinal residues and add water to decoct for another 1 hour, combine the decoctions, and concentrate to a specific gravity of 1.2 to 1.8 for use as a binder.
[0038] Spray the extract concentrate on the nanopowder original drug to make soft materials, pass through a 14-mesh sieve to make wet granules, dry at 50°C-60°C for 1.5h, pass through a 14-mesh sieve for granulation, and press into plain tablets.
[0039] Add low-methyl es...
Embodiment 2
[0041] The in vitro dissolution test of Chinese medicine colon tablet of embodiment 2 of the present invention
[0042] 1 Determination method of index component astragaloside IV
[0043] 1.1 Determination of maximum absorption wavelength of astragaloside IV
[0044] Accurately weigh 4.895 mg of the astragaloside reference substance, and dilute it to a 10 ml measuring bottle with a phosphate buffer solution of pH=8 to obtain an astragaloside reference substance solution with a concentration of 0.4895 mg / ml, and carry out ultraviolet-visible full-wavelength ( 190~900nm) scan. The maximum absorption wavelength was determined to be 538nm. There is no interference from other drugs in the prescription and calcium pectate at 538nm.
[0045] 1.2 Establishment of Astragaloside IV Standard Curve
[0046] Precisely draw 0.1, 0.2, 0.3, 0.5, 0.7 and 0.9ml of 0.4895mg / ml astragaloside reference substance solution into a 50ml measuring bottle, accurately add phosphate buffer to constant...
Embodiment 3
[0050] Dissolution test in vivo of Chinese medicine colon granule of embodiment 3 of the present invention
[0051] Make granules of the self-made traditional Chinese medicine tablets for treating ulcerative colitis, and wrap the above-mentioned self-made pectin calcium coating film; take 6 rabbits with a body weight of about 2 kg, and pour 0.2 g of the above-mentioned pectin calcium granules every 6 hours, canning 6 times . Rabbits were killed and dissected 3 hours after the last administration. An average of about 0.2 g of intact calcium pectin particles was found in the rabbit stomach, an average of 0.05 g of intact calcium pectin particles was found in the small intestine, and the rest were estimated to have been degraded in the cecum. The individual conditions of the 6 rabbits were basically similar.
