摘要(Abstract):

目的:采用HPLC建立草乌药材的指纹图谱。方法:Kromasil C18色谱柱(4.6 mm×250 mm,5μm);乙腈-醋酸铵缓冲溶液(2.5‰冰醋酸-浓氨水,pH 10.5)(60∶40)为流动相;流速1.0 mL.min-1;检测波长240 nm;柱温30℃。结果:精密度和重复性试验中各共有峰相对峰面积的RSD均小于2%,所得的色谱图各色谱峰分离较好,基线平整,符合指纹图谱有关规定。结论:本方法快速、简便、准确、重复性好,结果可靠,可为草乌药材的质量评价提供有效手段。
Objective: To establish the HPLC fingerprint of Radix Aconiti Kusnezoffii.Method: The chromatographic separation was performed on a Kromasil C_(18)(4.6 mm×250 mm,5 μm) eluted with a mobile phase of acetonitrile-ammonium acetate buffer(2.5‰ acetic acid-ammonia pH 10.5)(60∶40).The UV detection wavelength was set at 240 nm and the flow rate was set at 1.0 mL·min~(-1).Result: The RSD of precision and repeatability was less than 2%.Under the selected chromatographic conditions,good HPLC fingerprints of Radix Aconiti Kusnezoffii were obtained.Conclusion: The method was simple,accurate and repeatable.It can be used for the quality control of Radix Aconiti Kusnezoffii.
