| titleOfInvention | A kind of preparation method of high purity rhynchophylline monomer |
| abstract | The present invention relates to the preparation method of a kind of high purity rhynchophylline monomer, belong to active ingredient of Chinese herbs separating and purifying technology field.It comprises the following steps a, rhynchophyllin extract is splined on silica gel column chromatography, uses halogenated alkane alcohol system to elute, collects eluent, concentrates, obtain rhynchophyllin crude product；B, described rhynchophyllin dissolving crude product liquid is splined on high-speed counter-current chromatograph, the most respectively rhynchophyllin and corynoxeine monomer.The invention have the advantage that and can effectively prepare purity rhynchophyllin more than 96% and two kinds of monomers of corynoxeine. |
