中文摘要:
      目的: 通过测定白花前胡甲素、白花前胡乙素和紫花前胡苷的含量,建立筛查百花定喘制剂中投料为前胡还是紫花前胡的HPLC方法。方法:采用Symmentry-C18(4.6 mm×250 mm,5 μm)色谱柱,流动相:甲醇(A)-0.1%磷酸溶液(B),梯度洗脱,检测波长为321 nm,流速为1.0 mL·min-1结果:5批药材的标示名称与试验判断结果不一致;47批百花定喘制剂的筛查结果表明,未见紫花前胡投料,前胡存在投料不足的情况。结论:该方法专属性良好,可作为定性筛查白花定喘制剂中投料前胡的方法。
英文摘要:
      Objective: To develop an HPLC method for the determination of Praeruptorin A, Praeruptorin B and Nodakenin, so as to screen Peucedanum praeruptorum or Peucedanum decursivum in Baihua Dingchuan Preparations. Methods: The separation was performed with Waters Symmentry-C18(4.6 mm×250 mm, 5 μm) column. A gradient elution of methanol and 0.1% phosphoric acid solution were adopted as the mobile phase at a flow rate of 1.0 mL·min-1. The detection wavelength was 321 nm. Results: The 5 batches of medicinal materials were inconsistent with experimental result. In addition, Peucedanum decursivum was not found in 47 batches of Baihua Dingchuan Preparations, but Peucedanum praeruptorum was in shortage. Conclusion: The established method was specific, reliable and simple, which is adoptable for quality control of Peucedanum praeruptorum in Baihua Dingchuan Preparations.
