摘要: 建立一种同时测定壮瑶药狗仔花中咖啡酸和绿原酸含量的HPLC方法。色谱柱为Welch Ultimate XB-C18(4.6 mm×250 mm,5 μm);流动相为乙腈-0.2%磷酸水溶液,梯度洗脱;流量为1.0 mL/min;检测波长为327 nm;柱温为25 ℃。结果表明,绿原酸和咖啡酸分别在47.84~239.2 μg/mL(R=0.999 8)、10.05~50.25 μg/mL(R=0.999 9)呈现良好的线性关系,平均加样回收率分别为96.69%、102.10%,RSD分别为0.74%、2.00%。试验建立了HPLC法测定狗仔花中绿原酸、咖啡酸含量的方法,该方法准确、灵敏、可靠,重现性较好,可用于壮瑶药狗仔花的质量控制。

Abstract: To establish a method for the determination of caffeic acid and chlorogenic acid Vernonia patula by HPLC. The separation was performed on Welch Ultimate XB-C18(4.6 mm×250 mm,5 μm)with the acetonitrile-0.2% phosphoric acid aqueous solution as the mobile phase with gradient elution. The volume flow rate was 1.0 mL/min. The detection wavelength was 327 nm. The column temperature was 25 ℃. The linear range of caffeic acid and chlorogenic acid were 47.84~239.2 μg/mL(R=0.999 8)、10.05~50.25 μg/mL(R=0.999 9), and the average recoveries (n=6) were 96.69%(RSD=0.74%)、102.10%(RSD=2.00%). This paper established a method for the contents of chlorogenic acid and caffeic acid in Vernonia patula. The method is accurate, sensitive, credible and repeatable. It can be applied to the quality control of Vernonia patula.
