To discuss how to extract the indirubin of the higher purity from Indigo Naturalis.
After extracting the indirubin from Indigo Naturalis by acetic ether, compare the separation effect of the extract in Si gel column with that in alumina column.
The indirubin in Indigo Naturalis by Si gel column chromatography is chosen. The purity of indirubin is 98.3% after Si gel column chromatography.
The indiruhbin of the higher purity was attained by the simple experimental method.
