摘要
目的:建立测定利克飞龙原料有关物质的HPLC方法。方法:色谱柱为Kromasil C_(18)(250 mm×4.6 mm,5μm);流动相为甲醇-0.05%磷酸(85:15);检测波长为226 am;流速为0.9 ml·min^(-1);柱温为25℃;进样量为10μl。结果:各杂质峰与主峰分离度良好,检出限及定量限分别为0.20 ng及0.59 ng。结论:该方法灵敏度高、精密度好、专属性强,可用于利克飞龙原料有关物质的测定。
Objective: To establish a determination method for the related substances in the raw material of licofelone by HPLC. Methods: A Kromasil C 18 (250 mm×4.6 mm,5 μm) column was adopted with a mobile phase consisting of methanol-0.05% phos- phate (85:15 ) , the flow rate was 0.9 ml ·min^-1, the detection wavelength was set at 226nm, the column temperature was 25℃ and the injection volume was 10 μl. Results: The resolutions of the related substances were acceptable. The detection limit and the quanti- tation limit of the samples were 0.20ng and 0.59ng, respectively. Conclusion: The method is sensitive, accurate and specific, and can be used to determine the related substances in the raw material of licofelone.
