Abstract: The differential pulse polarographic behaviour of colchicine have been investigated. A well defined peak was observed in a 0.6% (C4H9)4NCl-B. R. buffer solution (pH 1.81) at potential Of -0.90 V(vs Ag/AgCl). An excellent linear relationship existed between the concentration(9.6×10-7~8.6×10-5mol/L) and peak current. This method provides a rapid and simple way to determine colchicine in pharmaceutical preparations and I phigenia indica Kunth et Benth.

Key words: colchicine, differential pulse polarography, determination
