A direct, simple and rapid high-performance liquid chromatographic method has been developed for the determination of ketoprofen with ibuprofen as internal standard. Samples were chromatographed on a 5 microm Kromasil 100 C18 column. The mobile phase was a mixture of acetonitrile-0.01 M KH2PO4 adjusted to pH 1.5 with orthophosphoric acid 85% (60:40, v/v). Detection was at 260 nm and the run time was 10 min. The detector response was found to be linear in the concentration range 0.02 to 40 microg/ml. This HPLC assay has been applied to measure the "in vitro" percutaneous penetration of ketoprofen through rat skin.
已开发出一种直接、简单且快速的高效液相色谱法,以布洛芬为内标物测定酮洛芬。样品在5微米的Kromasil 100 C18柱上进行色谱分析。流动相是乙腈与0.01M磷酸二氢钾的混合物,用85%的正磷酸调至pH 1.5(60:40,v/v)。检测波长为260nm,运行时间为10分钟。检测器响应在0.02至40微克/毫升的浓度范围内呈线性。该高效液相色谱法已应用于测定酮洛芬“体外”经大鼠皮肤的渗透情况。
