1. the industrial separation method of purification of a licoflavone series monomers, it is characterised in that include sweetGrass extractive of general flavone uses the step of process-scale chromatography column chromatography system isolated licoflavone series monomers;

  • Wherein, in process-scale chromatography column chromatography system, use the mixture of petroleum ether and dichloromethane as flowing phase,The mixed volume of petroleum ether and dichloromethane is than for 0-6 1;

    Elution process uses the mixed volume of petroleum ether to passThe mode subtracted carries out eluting, step by step eluting isolated licoflavone series monomers.
