Abstract

The invention discloses a synthesizing method for a separated and purified special resin for an assembled flavone of rhizome drynaria. in the synthesizing method,: divinylbenzene is taken as a cross-linking agent, GMA (glycidyl methacrylate) and methyl acrylate are taken as monomers, benzoyl peroxide is taken as an initiator, toluene and liquid paraffin wax are taken as a mixed hole-making reagent. The method comprises the following steps: mixing the materials into water and then stirring and aggregating; washing with water; washing with ethanol; repeatedly washing with water; centrifuging; and lastly using a wet column-filling method to fill the centrifuged resin into a resin column and leaching the resin column with an ethanol solution of sodium hydroxide, thereby acquiring the separated and purified special resin for the assembled flavone of rhizome drynaria. The separated and purified special resin for the assembled flavone of rhizome drynaria provided by the invention has the advantages that the stability is higher, the absorption capacity is high, the resin is easily cleaned, and the selectivity is high.

Description

technical field [0001] The invention relates to a method for synthesizing a resin, in particular to a method for synthesizing a special resin for separating and purifying drynaria total flavonoids. Background technique [0002] Drynaria is rich in resources, and has the functions of strengthening tendons and bones, nourishing kidney and solidifying essence, dispelling blood stasis and relieving pain. For the treatment of kidney deficiency, rheumatic bone pain, bruises, dysentery and so on. At present, drynaria is used in medicines, which has attracted people's attention, and the drug effect is very good. The resins currently on the market have the disadvantages of poor selectivity and rapid decline in adsorption capacity in terms of separating the active ingredients of drynaria. Therefore, a high-quality separation resin has been developed. Purifying the resin of drynaria total flavonoids is of great significance. Contents of the invention [0003] The invention provides...
