摘要
目的:建立测定八珍益母片中盐酸水苏碱含量的方法。方法:采用高效液相色谱法。色谱柱为KromasilNH2(200mm×4.6mm,5μm),流动相为乙腈-水(75:25,V/V),流速为1.0ml/min,柱温为30℃,检测波长为192nm,进样量为10μl。结果:盐酸水苏碱的进样量在0.6263~5.2190μg范围内与峰面积积分值呈良好的线性关系(r=0.9999);精密度、稳定性、重复性试验的RSD≤0.41%;平均加样回收率为98.50%,RSD=0.73%(n=6)。结论:本方法准确、快速、简便、可靠,可用于八珍益母片中盐酸水苏碱的含量测定。
OBJECTIVE : To establish a method for the content determination of stachydrine hydrochloride in Bazhen yimu tab-lets. METHODS: HPLC method was adopted. The determination was performed onKromasil NH2 (200mm×4.6mm,5μm) col-umn with mobile phase consisted of acetonitrile-water (75:25, V/V)at the flow rate of 1.0 ml/min. The column temperature was 30 ℃, and the detection wavelength was set at 192 nm. The sample size was 10 lal. RESULTS: The linear range of stachydrine hy-drochloride were 0.626 3-5.219 0 lag (r=0.999 9) with an average recovery of 98.50% (RSD=0.73%, n=6). RSDs of precision, reproducibility and stability tests were lower than 0.41%. CONCLUSIONS: The method is accurate, rapid, simple and reliable. It can be used for the content determination of stachydrine hydrochloride in Bazhen yimu tablets.
