摘  要:目的建立应用HPLC—uV同时测定玄参中4种主要活性成分——哈巴俄苷、肉桂酸、安格洛苷C和acteoside含量的方法。方法采用Hypersil BDS—C18色谱柱(4、0mm×250mm,5μm),流动相为乙腈和1%醋酸水溶液,梯度洗脱,流速1mL·min^-1,检测波长278nm,柱温25℃。结果哈巴俄苷、肉桂酸、安格洛苷C和acteoside线性范围分别为15、12—302、4mg·L^-1,7、72—154.4mg·L^-1,24、84~496、8mg·L^-1,6.64—132.8mg·L^-1;平均回收率(n=5)分别为101、59%(RSD=2、40%),96.75%(1.32%),100.11%(3.95%),99、89%(2、08%)。结论本方法简单、快速、准确可靠,可作为玄参药材的质量控制方法。OBJECTIVE To establish a HPLC-UV method for simultaneous determination of four kinds of bioactive components in Radix scrophulariae,i, e. harpagoside, cinnamic acid, angroside C and acteoside. METHODS The separation was performed on a Hyspersil BDS-CIs column (4.0 mm × 250 mm ,5μm), using a gradient elution with acetonitrile-water (containing 1, 0% acetic acid) as the mobile phose. The flow rate was 1.0 mL · min^-1, the detection wavelength was 278 nm and the temperature of column was 25 ℃. RESULTS The linear ranges of harpagoside, cinnamic acid, angoside C and acteoside were 15.12 - 302, 4 mg · L^-1 , 7.72 - 154.4 mg · L^-1 , 24. 84-496. 8 mg · L^-1 and 6. 64 - 132. 8 mg · L^-1 , respectively. The average recoveries (n =5) of the four constituents were 101.59% (RSD = 2.40%), 96.75% (1.32%), 100.11% (3.95%), 99.89% (2.08%), respectively. CONCLUSION The simple, rapid and reliable method could be used for the quality control of Radix scrophulariae.
