Method for preparing yerbadetajo herb polyferose complex and application thereof

Abstract

The invention relates to a method for preparing a yerbadetajo herb polyferose complex and application thereof, which can be used for effectively solving the problems existing in the preparation of the yerbadetajo herb polyferose complex and the preparation of a medicament for treating iron-deficiency anemia, can be effectively applied to food additives and can be used for improving the immunity of an organism. According to the technical scheme, the method comprises the following steps of: adding distilled water into dried yerbadetajo herb powder for warm soaking and filtering to obtain a yerbadetajo herb polysaccharide solution; adding an NaOH ionic solution into the yerbadetajo herb polysaccharide solution for adjusting the pH value, adding trisodium citrate and FeCl3, dropwise adding with stirring, adjusting the pH to 8-10 with the NaOH solution, immediately stopping dropwise adding an FeCl3 solution and an NaOH solution when a red insoluble matter appears in a reaction solution, centrifuging and removing precipitates to obtain a yerbadetajo herb polyferose complex solution; and dialyzing, depositing in alcohol to obtain precipitates, and washing the precipitates to obtain the yerbadetajo herb polyferose complex. The yerbadetajo herb polyferose complex can be taken as a food additive, can be applied to medicinal use, is a medicament for preventing and treating iron-deficiency anemia, and can be used for improving the immunity of an organism.

Description

technical field [0001] The invention relates to medicine, in particular to a preparation method and application of a polysaccharide-iron complex of Eclipta chinensis. Background technique [0002] Biomacromolecular metal complexes formed by the reaction of biomacromolecules and trace element metal ions under certain conditions show specific biological activities, such as amino acid and nucleic acid metal complexes. Amino acid metal complexes have been patented as feed additives. Such as amino acid and copper complex (Kaczmarek, University of Gdansk, Poland, etc.), glycine and ferric ion complex (Devore EC, Department of Chemistry, University of Wyoming, USA, etc.). The German published patent No. is 2209616 medicinal cysteine ​​and zinc complex formed as a zinc supplement, the method is to add zinc oxide aqueous solution in the cysteine ​​solution, adjust the pH with NaOH solution to form a complex thing. [0003] Another example is that U.S. Patent No. 3821192 discloses ...
