Embodiment 1
[0014] Embodiment 1 (with 1000 as base number, prepare buccal tablet, and enumerate in the mode of table)
[0015] a. Grind the screened gallic medicinal material to 5 meshes, extract once with 5 times the amount of solvent aqueous solution, the temperature is 30°C, the extraction time is 1 hour, the solvent is recovered, concentrated, and vacuum-dried to obtain a dry extract, which is crushed into powder , through a 60-mesh drug sieve to obtain a crude extract;
[0016] b. Dissolve the crude gallic extract in an aqueous solution, absorb it with a macroporous resin, and then elute it with an organic reagent ethanol solution with a concentration of 0-95%, collect the eluent, concentrate the eluent under reduced pressure, and dry it. The effective part of gallotannin is obtained, which contains 50% of total tannin by weight of dry product;
[0017] c, then further use preparative liquid chromatography and countercurrent chromatography to obtain the effective ingredients of gall...
Embodiment 2
[0023] Embodiment 2 (preparation of orally disintegrating tablets, and enumerating in the form of a table)
[0024] a. Crush the screened gallic medicinal material to 20 meshes, extract twice with 8 times the amount of solvent, at a temperature of 50°C, and extract for 2 hours each time, combine the extracts, recover the solvent, concentrate, and dry in vacuum to obtain dry infusion Paste, crushed into powder, passed through 80-mesh medicine sieve to obtain crude extract;
[0025] b. Dissolve the crude gallic extract with 60% ethanol aqueous solution, absorb it with Sephadex gel, elute with 0-95% methanol aqueous solution successively, collect the eluent, concentrate the eluent under reduced pressure, and dry , to obtain the effective fraction of gallic tannin, which contains 60% of total tannin by weight of dry product;
[0026] c, and then further prepare the active ingredients gallic acid, m-digallic acid, methyl gallate, 1,2,3,6-tetra-O-galloyl-β-D-glucose, 1,2, 3,4,6-Pe...
Embodiment 3
[0032] Embodiment 3 (preparation oral effervescent tablet, and enumerates in the mode of table)
[0033] a. Crush the screened gallic medicinal material to 40 mesh, extract 3 times with 10 times the amount of solvent at 70°C, and extract for 3 hours each time, combine the extracts, recover the solvent, concentrate, and spray dry to obtain dry infusion Paste, crushed into powder, passed through a 100-mesh medicine sieve to obtain crude extract;
[0034]b. Dissolve the crude gallic extract with 40% ethanol aqueous solution, absorb it with polyamide, elute with ethanol solution with a concentration of 0-95% successively, collect the eluent, concentrate the eluent under reduced pressure, and dry, that is The effective parts of gallic tannin are obtained, which contain 70% of total tannin by weight of dry product;
[0035] c, and then further prepare the active ingredients gallic acid, m-digallic acid, methyl gallate, 1,2,3,6-tetra-O-galloyl-β-D-glucose, 1,2, 3,4,6-Penta-O-galloy...
