Embodiment 1

[0046] Please refer to Table 1, using the suspension polymerization method to copolymerize industrial divinylbenzene (DVB) and polar monomer ethylene glycol methacrylate (EGDMA) to prepare the initial copolymer suspension double bond series resin; the initial macropore obtained by polymerization Adsorption resin PDVB-EGDMA, fully swelled in 3-10 times of organic solvent, added Friedel-Crafts catalyst (for example, anhydrous ferric chloride, etc.), at a temperature of 60-100 ° C, the suspension double The bonded post-crosslinking reaction produces a post-crosslinked macroporous adsorption resin with a high specific surface area. Reduce to room temperature, filter, wash with ethanol and soak overnight, add an appropriate amount of HCl aqueous solution to soak, wash with a large amount of water until the effluent water is neutral, wash with ethanol, dry in the air, and then vacuum-dry for later use.

[0047] The high specific surface polarity post-crosslinking adsorption resin is...

Abstract

The invention discloses past-crosslinking macroporous resin and application thereof to purification of an effective ingredient of peucedanum praeruptorum dunn. Polar monomer methylacrylic acid glycol ester (EGDMA) is adopted to modify suspended double-bond past-crosslinking divinylbenzene (DVB) macroporous resin, a high specific surface and polarity are achieved at the same time, and the past-crosslinking macroporous resin can be widely applied to separation and purification of the coumarin effective ingredient in the peucedanum praeruptorum dunn. Adopted raw materials are easy to obtain, the preparation method is simple, product cost is low, and pollution to the environment is small. The past-crosslinking macroporous resin can be used repeatedly, and the concentration of the coumarin effective ingredient in the peucedanum praeruptorum dunn can be raised to 50% or above.

Description

technical field [0001] The invention relates to the technical field of separation and purification of proscoumarins from white flowers, in particular to a cross-linked macroporous resin after hanging double bonds and its preparation and application in the separation and purification of proscoumarins from white flowers. Background technique [0002] Baihuaqianhu is a kind of traditional Chinese medicine Qianhu, alias: Qianhu (Famous Doctor Bielu), Jijiaqianhu, Guanqianhu (medicine name), Shanduhuo (Jiangsu Yixing), etc. It is a perennial erect herb with a height of 60~ 90 cm or slightly longer; root thick, conical, 3-15 cm long, branched, brown or yellowish brown; stem cylindrical, very strong, light green, with longitudinal lines, and many brown leaf sheaths at the base fiber. Baihua Qianhu is mainly produced in Anhui, Jiangxi, Zhejiang, Fujian, Guangxi, Hunan, Hubei, Sichuan and other places. The production of Baihua Qianhu in Ningguo City of Anhui Province ranks first in ...
