摘要：

A high-performance liquid chromatographic (HPLC) method for the simultaneous determination of sulfadoxine, pyrimethamine, mefloquine and the carboxylic metabolite of mefloquine in plasma is described. After the proteins have been precipitated with a combination of zinc sulphate and acetonitrile containing two internal standards, pyrimethamine and mefloquine are extracted as bases and sulfadoxine and the carboxylic metabolite of mefloquine as ion-pairs with tetrabutylammonium. The drugs are separated by HPLC on a 3-mu-m octadecylsilica column with ultraviolet detection at 229 nm. The method is simple and reliable and enables the simultaneous determination of the drugs in 600-mu-l plasma samples with a sensitivity suitable for standard drug monitoring purposes.
