TITLE: | |
摘要: | 目的:建立同时测定壮药冰糖草中野黄芩苷、蒙花苷含量的方法。方法:采用高效液相色谱法。色谱柱为Phenomenex C18,流动相为乙腈-0.05%磷酸(梯度洗脱),流速为1.0 ml/min,检测波长为330 nm,柱温30 ℃,进样量为10 μl。结果:野黄芩苷、蒙花苷检测质量浓度线性范围分别为0.015 8~0.316 8 mg/ml(r=0.999 9)、0.000 5~0.010 4 mg/ml(r=0.999 7);精密度、稳定性、重复性试验的RSD<3%;加样回收率分别为99.56%~102.38%(RSD=1.07%,n=6)、95.14%~98.29%(RSD=1.24%,n=6)。结论:该方法操作简便,稳定性、重复性好,可用于冰糖草中野黄芩苷、蒙花苷含量的同时测定。 |
ABSTRACT: | OBJECTIVE: To establish a method for the simultaneous determination of scutellarin and linarin in Scoparia dulcis. METHODS: HPLC was performed on the column of Phenomenex C18 with mobile phase of acetonitrile-0.05% phosphoric acid (gradient elution) at a flow rate of 1.0 ml/min, the detection wavelength was 330 nm, column temperature was 30 ℃, and the injection volume was 10 μl. RESULTS:The linear range was 0.015 8-0.316 8 mg/ml for scutellarin (r=0.999 9) and 0.000 5-0.010 4 mg/ml for linarin (r=0.999 7); RSDs of precision, stability and reproducibility tests were lower than 3%; recoveries were 99.56%-102.38%(RSD=1.07%,n=6) and 95.14%-98.29%(RSD=1.24%,n=6), respectively. CONCLUSIONS: The method is simple with good stability and reprodicibility,and can be used for the simultaneous determination of scutellarin and linarin in S. du- lcis. |
