摘要
目的:建立HPLC法检查小剂量阿司匹林片中游离水杨酸的方法。方法:以十八烷基硅烷键合硅胶为填充剂;乙腈-四氢呋喃-冰醋酸-水(23:5:5:61)为流动相;检测波长280nm。结果:水杨酸在0.1063~53.15μg/ml r=0.9999范围内呈良好线性,精密度试验:RSD=0.64%(n=6)。结论:本方法准确、可靠。可用于检查小剂量阿司匹林片中的游离水杨酸。
Objectire: To establish a HPLC method for testing free salicylic acid in small dose of aspirin tablets. Methods: The test was conducted on a DiamonsirIM C18 column ( 150 × 4.6mm, 5um ), using actetonitrile - tetrahydrofuran -glacial HAc- H2O(23:5: 5: 61) as mobile phase and a UV detector at 280nm.Results:The linear range for the method was 0.1063- 53 .15μg·ml^-1(r= 0.9999) .The method was precise with RSD of 0.64% for within-day variation(n= 6) .Condusion: Anaccurate and rapid HPLC method for testing free salicylic acid in small dose of aspirin tablets is established.
