摘 要:目的 建立高效液相色谱(HPLC)法测定瑞舒伐他汀钙原料药中有关物质的方法。方法 采用HPLC法,Phenomenex Luna C18 (2)色谱柱(250 mm×4.6 mm,5 μm),流动相为水-乙腈-1%三氟乙酸水溶液(62:37:1),体积流量为1.0 mL/min,柱温为40℃,进样量为20 μL,检测波长为242 nm。结果 系统和方法精密度RSD值均小于20%(n=6),瑞舒伐他汀钙在0.020 1~0.201 3 μg线性关系良好(r=0.999 8),瑞舒伐他汀钙的检测限为2.76 ng,各杂质氧化产物、内酯、光降解产物Ⅰ和Ⅱ和非对映异构体各杂质的检测限依次为1.85、1.32、1.08、1.11、2.06 ng。结论 本法合理严谨,精密度好,检测灵敏度高,可有效用于瑞舒伐他汀钙有关物质检测。Objective To establish an HPLC method for detecting the related substances ofrosuvastatin calcium. Methods HPLC was carried out on Phenomenex Luna C18 (2) column (250 mm× 4.6 mm, 5 μm) with water - acetonitrile - 1% trifluoroacetic acid (62 : 37 : 1) as mobile phase. The detection wavelength was 242 nm and injection volume was 20 μL at the flow rate of 1.0 mL/min. The column temperature was set for 40 ℃. Results The RSD values of method precision and system precision were less than 20% (n=6). The rosuvastatin calcium had a good linearity in the range of 0.020 1 μg - 0.201 3 μg (r=0.999 8). The detection limit of rosuvastatin calcium was 2.76 ng and the detection limits of impurity were oxidation product (1.85 ng), rosuvastatin lactone (1.32 ng), photodegradation product Ⅰ (1.08 ng), photodegradation product Ⅱ (1.11 ng), non enantiomer (2.06 ng), respectively. Conclusion The method with good precision and high sensitivity could be used for detecting the related substances of rosuvastatin calcium.
