【摘要】 目的:建立羊耳菊药材的高效液相指纹图谱,并对共有色谱峰进行指认,为其质量控制方法提出科学依据。方法:采用HPLC-DAD检测法,Agilent Eclipse Plus C18柱(2.1 mm×150 mm,1.8μm);流动相0.1%甲酸水-0.1%甲酸乙腈溶液梯度洗脱;柱温45℃;检测波长325 nm;流速0.3 m L·min-1。结果:对10批羊耳菊药材进行测定,标定了17个共有峰,指认了其中5个共有峰,10批羊耳菊药材的相似度均在0.95以上。结论:该方法可靠、简便,可用于羊耳菊药材的质量评价。更多还原

【Abstract】 Objective: This study is to establish the fingerprint and find out the common chromatographic peaks of Inula cappa by HPLC. Method: The HPLC analysis was performed onan Agilent Eclipse Plus C18 column( 2. 1 mm × 150 mm,1. 8 μm) with 0. 1% fomic acid aqueous solution-0. 1% fomic acid acetonitrile solution as mobile phase at a flow rate of 0. 3 mL ·min- 1; The detective wavelength is 325 nm; The column temperature is 45 ℃. Result: The results indicated that 5 of 17 common peaks were identified. The similarity about 10 groups of Inulacappais is over 0. 95. Conclusion: This method is able to be a scientific basis of quality assessment according to its convenient and reliable.更多还原
