Abstract

The invention discloses a method for removing gentiana straminea polysaccharide pigment by using a three-dimensional porous amino graphene decolorizing column. According to the method, three-dimensional porous amino graphene hydrogel is loaded into a chromatographic column to prepare the decolorizing column, then the decolorizing column is applied to the field of gentiana straminea polysaccharide pigment removal, the application and removal process is simple, and the method is economical, and the cost is appropriate; the prepared three-dimensional porous amino graphene decolorizing column is successfully applied to decolorization of various polysaccharides, the decolorization rate and the recovery rate are very high, the decolorization efficiency in the removal process is high, and the polysaccharide retention rate is high. Besides, the three-dimensional porous amino graphene decolorizing column provides superior practical functions, exceeds many traditional methods, and overcomes the problems of use of organic reagents, difficulty in reuse and the like. Tests prove that when the gentiana straminea polysaccharide is decolored by the method, the decoloring efficiency is more than 95%, and the polysaccharide retention rate is more than 95%.

Description

technical field [0001] The invention belongs to the field of refining and processing methods of plant active ingredients, and in particular relates to a method for removing genita polysaccharide pigments by a three-dimensional porous amino graphene decolorization column. Background technique [0002] Gentiana is a traditional Chinese medicinal material, belonging to the four authentic raw materials of Gentiana chinensis. Gentiana grows in Tibet, Qinghai, Sichuan and other places, and is popular on the Qinghai-Tibet Plateau. It is called "Xiejigabao" in Tibetan. At present, there have been many literature reports that the root of Gentiana twista is commonly used to treat rheumatism, damp-heat jaundice and so on. In Korea, Gentiana has been recorded as an active substance used in the production of functional food and pharmaceutical industries to improve age-related osteoarthritis. Due to the rapidly aging population, the demand for Gentiana is growing. The previous research...
