colchicine and its Impurities

Colchicine, in the form of the autumn crocus, has been used as early as 1500 BC to treat joint swelling. It is a medication used to treat gout and Behçet's disease. In gout, it is less preferred to NSAIDs or steroids.. Reference standards of Colchicine API, and its pharmacopeial, non pharmacopeial impurities, and stable isotopes are listed below
