Abstract: To establish a high performance liquid chromatography-ultraviolet (HPLC-UV) method for determination of several kinds of sulphonamides residues. By the analysis of the ultraviolet wavelength scanning to 13 kinds of sulfa drugs such as SD, SA, SQ, SUL, SMM, SMD, SDM', SIZ, ST, PST, SMZ, SST and ST-Na, 270 nm is used for detection wavelength. Due to the differences of pH value and structure among drugs, a variety of combinations methods were compared. Acetonitrile and acetate were used as mobile phase for gradient elution, which can separate 13 sulphonamides. There were 10 chromatographic peaks, three of ST-Na, PST and ST overlapped, and additionally two of SDM'and SMZ overlapped. The method to extract samples by acetonitrile-chloroform was proved to be good because of less interferences from impurities, over 80% recovery rate and faster analytical time.
