摘要: 本文建立了一种用于新药那格列奈片含量测定的稳定性指示HPLC, 并对方法的选择性、准确性、精密度、检测限和定量限等进行了认证. 采用C18色谱柱, 以乙腈-甲醇-磷酸盐缓冲液(70:4:l20, v/v/v, pH6.6) 为流动相, 流速为1.0mL·min-1, 检测波长为216nm. 线性范围为4.94-49.9μg·mL-1 (r = 0.9999, n = 5), 平均回收率为99.9 (RSD = 0.5%, n = 9), 精密度为0.3% (n = 6). 本法选择性好、准确度高, 可用于那格列奈片的含量测定.

Abstract: A stability-indicating HPLC method is described for the determination of nateglinide in a new tablet formulation. Chromatographic separation was achieved using a mobile phase consisting of acetonitrile, methanol and phosphate buffer(70:4:20, v/v/v, pH 6.6) at a flow rate of 1.0 mL·min-1 on a Hypersil BDS C18 column. Detection was carried out using a UV detector at 216 nm. The detector response was linear in the range of 4.94-49.4 μg·mL-1 for nateglinide. The described method was validated with respect to selectivity, precision, accuracy and limits of detection and quantitation.
