An HPLC method was established for the determination of dihydroergotoxine mesylate in dihydroergotoxine mesylate sustained release tablets. A C_(18) column was used with the mobile phase of 0.02 mol/L sodium bicarbonate solution (adjusted to pH 9.0 with sodium hydroxide solution)-acetonitrile (60 : 40) at the detection wavelength of 220 nm. The calibration curve was linear in the dihydroergotoxine mesylate concentration range of 1 -20 μg/ml. The average recovery was 99.1%.
