摘　　要：目的　采用分光光度法测定氯诺昔康注射液的含量。 方法 　以水为溶媒 ,测定波长 3 78nm的条件下 ,对氯诺昔康注射液进行含量测定 ,另外还对样品的测定条件进行了优选。结果 　氯诺昔康浓度在 4μg～ 2 0 μg范围内线性良好 ,以标准曲线法得其回收率为 99.7% (n=5 ) ,RSD为0 .78%。 结论 　该方法稳定可靠 ,重现性好 。OBJECTIVE A spectrophotometry method was developed for the determinaation of Lornoxicam in Lornoxicam for injection.METHODS It was determined by using water as the solvent at 378nm. The condition of determination for sample was optimized.RESULTS A good linearity can be found in the range of 4μg～20μg. The average recovery was 99 7%.and RSD was not more 0 8%.CONCLUSION The method is simple,rapid,and reproducible for determination of Lomoxicam in Lornoxicam injection
