Publication date: 2010
Publication number: CN101337960

Abstract: The invention discloses a method for extracting matrine from a sophora flavescens ait, which comprises three steps as follows: matrine molecular imprinting polymer is prepared, matrine molecular imprinting polymer is used as solid-phase extraction medium, and a matrine molecular imprinting solid-phase extraction column is used for extracting and separating matrine. A novel continuous rodlike molecule imprinting polymer which is synthesized by taking matrine as template molecules has the specific capacity for recognizing matrine; obtained polymer is prepared into the solid-phase extraction column through the means of packing or direct synthesis in the column; the method can be used for extraction, separation and purification of matrine; the obtained product has high purity quotient, the operating procedure is simple, the solvent usage is reduced, the extraction is safer and environment-friendly, and the purposes of removing impurities as well as purifying and enriching matrine can be served.
