Abstract:
AIM: To study the suitable conditions of the extraction-separation process of the indirubin in Folium Isatidis with NIR. METHODS: The indirubin was chromatographed on an aluminium oxide column and chloroform-ethyl acetate as eluting agent,eluate was recrystalized by methanol-acetone. RESULTS: The indirubin extracted by this method was of high purity (97.78%).The sample purity was similar to reference substance one((98.01%)).The spectra of NMR and IR are the same. CONCLUSION: This method is proved to be fast,safe,lower cost,simple and has good results.
