OBJECTIVE: To establish a RP- HPLC method to simultaneouslydetermine the contents of piperacillin and tazobactam. METHODS: Using μ Bondapak C18 column as fixed phase, a mixture of methanol and purified water( 34. 5∶ 65. 5) as mobile phase, and caffeine as internal standard, detecting wavelength: 220nm, flow rate: 1. 0ml/min. RESULTS: The linear rangs of piperacillin and tazobactam were 40~ 200μ g/ml and 5. 0~ 25. 0μ g/ml respectively. The average recovery and RSD ( n=5) were ( 100. 2± 0. 61) % for piperacillin and ( 99. 03± 0. 90) % for tazobactam. CONCLUSION: This method is rapid, simple and accurate.
