Problems solved by technology

[0003] After flavonoids are extracted from plants, they need to be purified and processed. The product after traditional solvent extraction has low purity and many impurities, and needs to be further extracted and purified. The methods usually used are resin adsorption and liquid chromatography separation. The cost of liquid chromatography separation High, and relatively low efficiency, resin adsorption has the advantages of high efficiency and good flavone purification effect, the adsorption resin used in the existing flavone resin adsorption is a general-purpose adsorption resin, the specific surface area of ​​the adsorption resin is limited, and the adsorption capacity is small

Abstract

The invention discloses a preparation method of an adsorbent resin used for plant flavone extraction. The preparation method comprises the following steps: using surface active agent modified nano calcium carbonate crystal whiskers, then using modified calcium carbonate crystal whiskers to be matched with a pore-foaming agent, using methyl methacrylate, styrene and sodium methacrylate to polymerize and prepare resin by using an antiphase emulsifiable method, and then preparing diluted hydrochloric acid to remove calcium carbonate inside the resin to obtain the adsorbent resin. The adsorbent resin prepared in the invention has the advantages of large specific surface area, more pore canals and large adsorbing capacity for flavone.

Description

technical field [0001] The invention relates to a preparation method of an adsorption resin for extracting plant flavonoids. Background technique [0002] Flavonoids have a wide range of pharmacological activities, are widely distributed, and are of various types. They are an important class of compounds in natural products. Bamboo leaf flavonoids are one of the main active ingredients of bamboo leaf extract, and the content in bamboo leaves accounts for 1-2%. Mainly, at the same time, it also contains flavonoids such as luteolin and apigenin. Compared with oxypreflavone, bamboo leaf flavonoid has a stable structure, is not easy to degrade, and has strong food safety. Because of its strong ability to scavenge free radicals, it has good anti-inflammatory, antibacterial, blood fat-lowering, anti-radiation, anti-cancer, anti-aging, improving cardiovascular system and brain nervous system functions. Therefore, it has broad market prospects in the fields of food additives, nat...
