| titleOfInvention | The method for extraction and purification of total flavones and agrimophol in Radix Agrimoniae |
| abstract | The invention belongs to active ingredient of Chinese herbs and purify field, disclose the method for extraction and purification of total flavones and agrimophol in a kind of Radix Agrimoniae, the method takes after Radix Agrimoniae is dried and sieves, and powder is carried out surname extraction and obtains Radix Agrimoniae Flavonoid extract; Keep the constant replacing backflow of powder to extract and obtain Radix Agrimoniae agrimophol extractum; Gained Radix Agrimoniae Flavonoid extract is crossed macroporous adsorptive resins eluting, concentrate eluant, is drying to obtain Radix Agrimoniae flavone; Radix Agrimoniae agrimophol extractum is made into concentrated solution and crosses macroporous adsorptive resins, be washed till colourless after carry out eluting, eluent recrystallization, be drying to obtain agrimophol crystal. The present invention adopts the method for twice surname extraction to separate the total flavones in Radix Agrimoniae and agrimophol, respectively obtain the extractum of total flavones and agrimophol, the extractum of total flavones and agrimophol is purified by the method in conjunction with macroporous adsorbent resin, obtain highly purified Radix Agrimoniae flavone and two products of agrimophol, the utilization rate that the method is effectively increased in Radix Agrimoniae active component. |
