Abstract
Objective:
To discuss how to extract the indirubin of the higher purity from Indigo Naturalis.
Methods:
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.
Results:
The indirubin in Indigo Naturalis by Si gel column chromatography is chosen. The purity of indirubin is 98.3% after Si gel column chromatography.
Conclusion:
The indiruhbin of the higher purity was attained by the simple experimental method.
