Abstract

The invention discloses a method for controlling the feed ratio of iron-dextran production by measuring the content of sugar anhydride. The method comprises the following steps of (1) detecting the iron content in an iron-dextran complexing solution, (2) preparing a test sample from the iron-dextran complexing solution, (3) sequentially cooling a sample to be tested, mixing the sample with an anthrone sulfuric acid solution, heating, cooling, and determining absorbance, (4) using water as blank control, (5) preparing the D-glucosum anhydricum into five standard solutions with different concentrations, (6) respectively measuring the absorbance of the five standard solutions with different concentrations, and making a standard curve according to the concentrations and the absorbance to obtain an equation, (7) calculating the absorbance of the sample to be tested according to the equation in the step (6) to obtain the concentration of glucose, and converting to obtain the content of the sugar anhydride, and (8) according to the iron content and the content of the sugar anhydride, converting the content of the sugar anhydride in the product with the corresponding specification, so as to adjust and control the feeding ratio of the sugar anhydride to the iron in the production process of the iron dextran.

Description

technical field [0001] The invention belongs to the technical field of drug detection and production, and in particular relates to a method for controlling the feeding ratio of iron dextran production by measuring the content of glucosinolate. Background technique [0002] Iron dextran complex solution is obtained by chemical (complexing) reaction of dextran with ferric chloride solution after hydrolysis and alkalization, and is an intermediate product in the production process of iron dextran. Iron dextran (iron dextran) is the raw material of iron dextran for injection. It is suitable for iron deficiency anemia in foals, calves, piglets, puppies and fur animals. It is an anti-anemia drug. Iron is the main component of hemoglobin and myoglobin, which is the main oxygen carrier in red blood cells. Myoglobin is the place where muscle cells store oxygen to meet the oxygen supply needs of muscles during exercise. Most enzymes and factors involved in the Krebs cycle contain ir...
