Abstract

The invention discloses a preparation process of aluminum magnesium alginate. The preparation process is characterized by comprising steps as follows: (1) an excessive amount of alginic acid and compound magnesium salt are subjected to a neutralization reaction for 15-20 min; (2) an excessive amount of aluminum carbonate is added for a neutralization reaction; (3) centrifugation is performed after complete reaction, and a centrifuged product is roughly crushed and dissolved in water; (4) after complete dissolution, centrifugation is performed, water insoluble substances are removed, and ethanol precipitation is performed on a water solution; (5) finally, the aluminum magnesium alginate is prepared through centrifugation, freeze drying and crushing. The prepared aluminum magnesium alginate contains alginic acid, magnesium ions, aluminum ions, carbonate and bicarbonate radical in the molecule structure, has biological activity of both neutralization acid and alginic acid, has multiple functions of protection of stomach and intestinal mucosa, neutralization of gastric acid, reduction of stomach proteinase activity and the like, is a high-quality crude drug and has good new drug development value.

Description

technical field [0001] The invention relates to a preparation process and application of a bulk drug, in particular to a preparation process of aluminum magnesium alginate. Background technique [0002] Stomach disease has become a very common type of disease in today's rapidly developing society, which seriously threatens human health. At present, there are many kinds of stomach medicines on the market, which can be divided into four categories: gastric acid neutralizing medicines, gastric acid suppressing gastric medicines, mucosal protecting gastric medicines and gastric motility promoting gastric medicines. Gastric drugs, but the action time of these drugs is relatively short, and the side effects such as secondary gastric acid, belching, bleeding, and alkalinization of urine are caused by the rapid release of effective groups; gastric drugs for protecting mucosa are The most popular stomach medicine at present, its function is not only to form a barrier to protect the ...
