    Abstract
    The aim of this study was to develop and validate a novel HPLC method for the simultaneous analysis of artemisone, clofazimine and decoquinate. Detection was obtained at two wavelengths; 284 nm (clofazimine) and 210 nm (artemisone and decoquinate). Gradient elution was used with mobile phase A (A) consisting of 0.005 M sodium octanesulphonic-acid (pH 3.5) and mobile phase B (B) of HPLC grade acetonitrile. The flow rate was set to 1.0 ml/min with (A) at 35% and (B) at 65% for 2 min, followed by a gradient shift of 10/90% ((A)/(B)) over a duration of 4 min. After 10 min, the initial gradient conditions were readjusted to 35/65% ((A)/(B)). Distinctive peaks were identified for clofazimine, artemisone and decoquinate, respectively. The proposed HPLC assay method was validated and found to be reliable, reproducible and accurate for simultaneous analysis of the three compounds
