TITLE:
摘要: 目的:建立同时测定石淋通片中新西兰牡荆苷2、新西兰牡荆苷1、夏佛塔苷含量的方法。方法:采用高效液相色谱法。色谱柱为Phenomenex C18,流动相为甲醇-0.1%磷酸水溶液( 梯度洗脱),流速为0.8 ml/min,检测波长为334 nm,柱温为25 ℃,进样量为10 μl。结果:新西兰牡荆苷2、新西兰牡荆苷1、夏佛塔苷的检测进样量线性范围分别为0.31~3.10、0.28~2.80、0.39~3.90 μg(r=0.999 9);精密度、稳定性、重复性试验的RSD<3.0%;加样回收率分别为95.2%~100.4%、96.3%~100.8%、95.7%~100.9%,RSD分别为1.6%、1.4%、1.7%(n=9)。结论:该方法简单、灵敏、准确、可靠,重复性好,可用于石淋通片的质量控制。
ABSTRACT: OBJECTIVE:To establish a method for simultaneous determination of vicexin 2, vicexin 1 and schaftoside in Shilintong tablet. METHODS: HPLC was performed on the column of Phenomenex C18 with mobile phase of methanol -0.1% phosphoric acid (gradient elution)at the flow rate of 0.8 ml/min, the detection wavelength was 334 nm, the column temperature was 25 ℃, and the injection volume was 10 μl. RESULTS: The linear range was 0.31-3.10 μg for vicexin 2 (r=0.999 9), 0.28-2.80 μg for vicexin 1 (r=0.999 9) and 0.39-3.90 μg for schaftoside (r=0.999 9), respectively;RSDs of precision, stability and reproducibility tests were lower than 3.0%;recoveries were 95.2%-100.4%(RSD=1.6%,n=9),96.3%-100.8%(RSD=1.4%,n=9) and 95.7%-100.9%(RSD=1.7%,n=9), respectively. CONCLUSIONS: The method is simple, sensitive ,accurate,reliable and reproducible, and can be used for the quality control of Shilintong tablet.
