TITLE:
摘要: 目的:建立同时测定夏荔芪胶囊中毛蕊异黄酮葡萄糖苷、特女贞苷、盐酸巴马汀、盐酸小檗碱、迷迭香酸含量的方法。方法:采用超高效液相色谱法。色谱柱为Shield RP18,流动相为乙腈-0.2%甲酸水溶液(梯度洗脱),流速为0.2 ml/min,柱温为35 ℃,检测波长为240 nm,进样量为1 μl。结果:毛蕊异黄酮葡萄糖苷、特女贞苷、盐酸巴马汀、盐酸小檗碱、迷迭香酸检测质量浓度线性范围分别为0.619~39.6、1.181~115.6、0.89~57.2、1.16~74、2.47~157.8 μg/ml(r均0.999 9);精密度、稳定性、重复性试验的RSD<3%;加样回收率分别为97.98%~102.44%、97.37%~100.96%、98.53%~102.30%、97.06%~102.21%、100.10%~102.25%,RSD分别为1.49%、1.13%、1.40%、1.46%、0.68%(n=9)。结论:该方法简单快速、准确性好,可用于控制夏荔芪胶囊的质量。
ABSTRACT: OBJECTIVE:To establish a method for simultaneous determination of calycosin-7-glucoside, specnuezhenide, berberine hydrochloride, palmatine hydrochloride and rosmarinic acid in Xialiqi capsule. METHODS: UPLC was performed on the column of Shield RP18 with mobile phase of nitrile -0.2% formic acid (gradient elution) at a flow rate of 0.2 ml/min, the column temperature was 35 ℃, the detection wavelength was 240 nm, and the injection volume was 1 μl. RESULTS: The linear range was 0.619-39.6 μg/ml for calycosin-7-glucoside (r=0.999 9), 1.181-115.6 μg/ml for specnuezhenide (r=0.999 9),0.89-57.2 μg/ml for berberine hydrochloride(r=0.999 9),1.16-74 μg/ml for palmatine hydrochloride(r=0.999 9) and 2.47-157.8 μg/ml for rosmarinic acid(r=0.999 9); RSDs of precision, stability and reproducibility tests were lower than 3%, recoveries were 97.98%-102.44%(RSD=1.49%,n=9), 97.37%-100.96%(RSD=1.13%,n=9), 98.53%-102.30% (RSD=1.40%,n=9), 97.06%-102.21%(RSD=1.46%,n=9) and 100.10%-102.25%(RSD=0.68%,n=9), respectively. CONCLUSIONS: The method is simple, rapid and reproducible, and can be used for the quality control of Xialiqi capsule.
