Abstract

The invention discloses a process for extracting perrotetin D. The process comprises the following steps: adding an ethanol solution into radula perrottetii gott serving as a raw material, extracting with microwaves, recycling ethanol from the extracting solution, dissolving the extract with hot water, adding to a macroporous resin column for adsorption, eluting, ultrafiltering the eluent by using an ultrafiltration membrane, concentrating by using a nanofiltration membrane, drying to obtain a crude product, dissolving the crude product by using hot water, standing for precipitating, and filtering so as to obtain perrotetin D. The process has the advantages and practical values that the perrotetin D prepared by using the method is high in purity, simple and convenient in method and can be put into industrialization easily.

Description

technical field [0001] The invention relates to a process for purifying calyxanin, which belongs to the field of medicine. Background technique [0002] Perrotetin D, the molecular formula is C 19 h 20 o 3 , molecular weight 296.37, structural formula: [0003] [0004] Ninglienin is derived from Radula perrottetii Gott. in the family Radulaceae. Modern pharmacological studies have shown that Ningliphyllin can inhibit the activity of 5-lipoxygenase, and its IC50 is 0.66 μ M / L; inhibit the activity of cyclooxygenase; anti-lipid peroxidation activity. [0005] At present, there is no relevant report on the industrial separation and preparation method of Ningbiancalycin in China. Contents of the invention [0006] The purpose of the present invention is to provide a simple and high-yielding process for purifying calyxin. [0007] The present invention is achieved through the following technical solutions: [0008] 1) Carry out microwave extraction on the calyx ...
