篇名: RP-HPLC法测定盐酸左西替利嗪咀嚼片中的有关物质
TITLE:
摘要: 目的:建立测定盐酸左西替利嗪咀嚼片中有关物质的方法。方法:采用反相高效液相色谱法。色谱柱为Venusil XBP-CN,流动相为乙腈-0.05 mol/L磷酸二氢钠溶液(以磷酸调节pH至3.0)(60 ∶ 40,V/V),检测波长为230 nm,流速为1.0 ml/min,柱温为25 ℃,进样量为20 μl。结果:盐酸左西替利嗪与有关物质分离度良好;盐酸左西替利嗪检测质量浓度线性范围为1.2~2.8 μg/ml(r=0.999 9);定量限和检测限分别为1.4、0.3 ng/ml;精密度、稳定性、重复性试验的RSD<1%;加样回收率为96.3%~105.0%,RSD=1.7%(n=9);样品中有关物质含量≤0.17%。结论:该方法操作简单,灵敏度高,重复性好,结果准确、可靠,可用于盐酸左西替利嗪原料药及其制剂的有关物质测定。
ABSTRACT: OBJECTIVE: To establish a method for the determination of related substances in Levo-cetirizine hydrochloride chewable tablet. METHODS: RP-HPLC was performed on the column of Venusil XBP-CN with mobile phase of acetonitrile-0.05 mol/L Sodium dihydrogen phosphate solution(pH value adjusted to 3.0 by phosphoric acid)(60 ∶ 40,V/V) at a flow rate of 1.0 ml/min, the detection wavelength was 230 nm, column temperature was 25 ℃, and volume injection was 20 μl. RESULTS: Levo-cetirizine hydrochloride chewable tablet showed good separation with related substances; the linear range of levo-cetirizine hydrochloride was 1.2-2.8 μg/ml (r=0.999 9); the quantification limit and detection limit was 1.4 ng/ml and 0.3 ng/ml, respectively; RSDs of precision, stability and reproducibility tests were lower than 1%; recovery was 96.3%-105.0% (RSD=1.7%,n=9); the contents of related substances were no more than 0.17%. CONCLUSIONS: The method is simple, sensitive, reproducible, accurate and reliable, and can be used for the determination of related substances in Levo-cetirizine hydrochloride chewable tablet.
