TITLE:
摘要: 目的:建立同时测定疏表灵颗粒中绿原酸、橙皮苷、黄芩苷含量的方法。方法:采用高效液相色谱法。色谱柱为SAGA Tri-Sal C18,流动相为乙腈-0.5%磷酸(梯度洗脱),流速为1.0 ml/min,检测波长为320 nm,柱温为30 ℃,进样量为10 μl。结果:绿原酸、橙皮苷、黄芩苷的检测质量浓度线性范围分别为2.463~240.5 μg/ml(r=0.999 9)、6.577~642.3 μg/ml(r=0.999 8)、1.708~166.8 μg/ml(r=0.999 8);精密度、稳定性、重复性试验的RSD≤1.8%;加样回收率分别为97.02%~102.40%(RSD=1.9%,n=6)、96.55%~100.20%(RSD=1.6%,n=6)、97.51%~100.70%(RSD=1.2%,n=6)。结论:该方法操作简便,结果准确、灵敏度高、重复性好,可用于疏表灵颗粒中绿原酸、橙皮苷、黄芩苷含量的同时测定。
ABSTRACT: OBJECTIVE: To establish a method for the simultaneous determination of chlorogenic acid, hesperidin and baicalin in Shubiaoling granule. METHODS: HPLC was performed on the column of SAGA Tri-Sal C18 with mobile phase of acetonitrile - 0.5% phosphoric acid (gradient elution) at a flow rate of 1.0 ml/min, detection wavelength was 320 nm, column temperature was 30 ℃, injection volume was 10 μl. RESULTS: The linear range was 2.463-240.5 μg/ml for chlorogenic acid (r=0.999 9), 6.577-642.3 μg/ml for hesperidin (r=0.999 8) and 1.708-166.8 μg/ml for baicalin (r=0.999 8); RSDs of precision, stability and reproducibility tests were no more than 1.8%; recoveries were 97.02%-102.40% (RSD=1.9%,n=6),96.55%-100.20%(RSD=1.6%,n=6) and 97.51%-100.70% (RSD=1.2%,n=6), respectively. CONCLUSIONS: The method is simple, accurate with high sensitivity and good reprosucibility, and can be used for the simultaneous determination of chlorogenic acid, hesperidin and baicalin in Shubiaoling granule.
