TITLE:
摘要: 目的:建立测定盐酸氯卡色林原料药中有关物质的方法。方法:采用高效液相色谱法。色谱柱为Welch ultimate XB-ODS,流动相为磷酸二氢钠溶液(pH为6.5)-乙腈(梯度洗脱),流速为1.0 mL/min,检测波长为220 nm,柱温为35 ℃,进样量为20 μL。结果:杂质1、2、3检测质量浓度线性范围分别为0.075 60~7.560 μg/mL(r=0.999 9)、0.081 40~8.140 μg/mL(r=0.999 9)、0.099 24~9.924 μg/mL(r=0.999 9);定量限分别为0.075 60、0.081 40、0.099 25 μg/mL,检测限分别为0.022 68、0.024 42、0.029 77 μg/mL;精密度试验的RSD<2.0%,稳定性、重复性试验只检出杂质1,RSD<2.0%;回收率分别为98.53%~102.45%(RSD=1.06%,n=9)、98.26%~101.64%(RSD=1.03%,n=9)、100.08%~102.10%(RSD=0.70%,n=9)。结论:该方法灵敏、快速、准确、可靠,可用于盐酸氯卡色林原料药中有关物质的测定。
ABSTRACT: OBJECTIVE: To establish a method for the determination of related substances in lorcaserin hydrochloride. METHODS: HPLC method was adopted. The determination was performed on Welch ultimate XB-ODS column with mobile phase consisted of Sodium dihydrogen phosphate(pH=6.5)-acetonitrile (gradient elution) at the flow rate of 1.0 mL/min. The detection wavelength was set at 220 nm, and column temperature was 35 ℃. The sample size was 20 μL. RESULTS: The linear ranges of impurity 1, 2, 3 were 0.075 60-7.560 μg/mL(r=0.999 9), 0.081 40-8.140 μg/mL(r=0.999 9), 0.099 24-9.924 μg/mL(r=0.999 9), respectively. The limits of quantification were 0.075 60, 0.081 40, 0.099 25 μg/mL. The limits of detection were 0.022 68, 0.024 42, 0.029 77 μg/mL. RSD of precision test was lower than 2.0%. Impurity 1 was found in stability test and reproducibility test,RSD<2.0%. The recoveries were 98.53%-102.45%(RSD=1.06%,n=9), 98.26%-101.64%(RSD=1.03%,n=9), 100.08%-102.10%(RSD=0.70%,n=9), respectively. CONCLUSIONS: The method is sensitive, rapid, accurate and reliable, which can be used to determine the related substances of lorcaserin hydrochloride.
