Lotus root polyferose compound, and preparation method and application thereof

The invention discloses a lotus root polyferose compound, and a preparation method and application thereof. The preparation method comprises the following steps: carrying out a contact reaction on lotus root polysaccharide and FeCl3 in the presence of a pH regulator, water and a catalyst, and carrying out cooling and separating purification to obtain the lotus root polyferose compound. According to the invention, the lotus root polysaccharide is adopted as a glycoside to react with ferric chloride to prepare the polyferose under catalysis of trisodium citrate, and optimization of condition selection can be carried out, so that the iron content can be greatly improved. 本发明公开了一种莲藕多糖铁复合物及其制备方法和应用，该制备方法包括：在pH调节剂、水和催化剂的存在下，将莲藕多糖和FeCl进行接触反应，冷却、分离纯化，得到莲藕多糖铁复合物。本发明采用莲藕多糖作为配糖体，在柠檬酸三钠催化下，和三氯化铁反应制备多糖铁，并进行了条件选择的优化，能够使铁含量有很大提高。
