RP-HPLC测定小鼠肿瘤组织中洛莫司汀的含量
Determination of the Content of Lomustine in Mouse Tumor Tissue by RP-HPLC
【摘要】 目的:以反相高效液相外标法测定小鼠肿瘤组织内洛莫司汀的含量。方法:应用乙腈-水(54:46)为流动相,在C18(5um)色谱柱上进行测定。结果:洛莫司汀的检测线性范围为0.98~15,68ug/ml,r=0.9 999。回收率为68.64%(n=9)RSD为0.32%。结论:本法简便、快速、灵敏、重现性好。
【Abstract】 OBJECTIVE: To determine the content of lomustine in mouse tumor tissue. METHODS: Lomustine was separated and determined on a reverse-phase C18 5um column with a mobile phase of acetonitrile-H2O(54 : 46), detected at 254nm and no internal standard. RESULTS: The ca[ibration curve was 1ineaI(r = 0. 9 999) within the range of 0. 98- 15. 68ug/ml for lomus tine. The recovery ratio of lomustine was 68. 64% (n = 9). The relative standard deviation(RSD) was 0. 32%. CONCLUSION: This method is simple and accurate
