Chemical study of betaines isolated from the whole stillage

Abstract

The solution of the problem of import substitution by creating domestic medications similar to foreign pharmacological efficacy and safety, especially given the availability of raw materials and high profitability of the target product, represents the current trend in the development of pharmacy. This fully applies to drugs based on betaine, the isolation of which was first proposed from the post-alcohol corn bard - a multitonous and cheap secondary raw material, obtained in production conditions using traditional alcohol technologies. A method for isolating betaine hydrochloride from a bard, including the original (separation into liquid and solid phases, removal of carbohydrates from the liquid phase, neutralization thereof) and known (separation from the liquid phase of betaine hydrochloride, liberated from glutamic acid, humic acids, metal chlorides) greater by 2-4 times the technological yield (0.4%). The task of establishing analytical indicators of the target product was carried out in comparison with the standard sample obtained from the tablets Acidin-Pepsin, imported to Russia from the Republic of Belarus. Both test samples (the target product and the standard sample) are characterized by their identical physical and chemical characteristics (description, solubility in water and alcohol, pH 1% of aqueous solutions), positive results of authenticity reactions (thermal decomposition, precipitating with copper (II) ions and silver nitrate), quantitative content (respectively 99.2 and 99.9%). The high technological yield of betaine hydrochloride isolated from the post-alcohol corn bard, identical to the standard sample for the most important analytical indicators, creates the prospect of solving the problem of import substitution of the drug "Acidin-pepsin", which requires the need for in-depth preclinical testing.
