Принадлежит:

The invention belongs to the technical field of bioactive substance extraction, and particularly relates to a column chromatography extraction method of flavone in peony seed shells. The method comprises the following steps: extracting a crude flavone extract from peony seed shells; and then separating and purifying the flavone in the peony seed shells by combining an S-8 macroporous resin-C18 silica gel column. A macroporous resin separation sample contains three flavonoid compounds, so that the adsorption selectivity on antibacterial active substances is high, and the obtained separation component has good antibacterial activity on escherichia coli and staphylococcus aureus; according to the present invention, the Penicifolin monomer is obtained after the secondary separation with the C18 silica gel column, the recovery rate can achieve 98.33 +/-0.64%, which is about 72.91% higher than the recovery rate of the Penicifolin in the crude extraction sample, the separation effect of the Penicifolin ...
