摘要
目的 建立一种高效液相色谱法测定复方替加氟胶囊含量及其溶出度。方法 采用Diamonsil C18柱 (5 μm ,4 .6mm×2 5 0mm) ,用冰醋酸调节甲醇 2mmol·L-1庚烷磺酸钠溶液 (10∶90 ) pH值至 3.5 0 ,抽滤后 ,每 10 0 0mL溶液加乙醚 2mL为流动相 ,流速为 1.0mL·min-1,UV检测波长为 2 80nm。结果 此方法线性关系良好 ,替加氟与尿嘧啶的平均回收率为10 0 .0 % ,10 0 .7% ,RSD为 0 .2 1% ,0 .98% (n =9)。结论 本方法简单、快速、结果准确可靠 ,为控制复方替加氟胶囊的质量提供了依据。
OBJECTIVE: A HPLC method was established for the determination of tegafur and uracil in compound tegafur capsules and its dissolution. METHODS: The chromatographic condition was as following:Diamonsil C18 column (5 μm, 4.6 mm × 250 mm); methanol and 2 mmol·L-1 sodium sulphonate heptane solution (10:90, adjusted pH to 3.50 by acetic acid), with 2 mL diethyl ether to 1000 mL solution as the mobile phase. The flow rate was 1.0 mL·min-1. The wavelength of detection was 280 nm. RESULTS: The mean recoveries of tegafur and uracil were 100.0% and 100.7% with RSD 0.21% and 0. 98% (n = 9) respectively. CONCLUSION: The proposed method appeared bo be simple, rapid, accurate and reliable.
