羊耳菊药材的HPLC指纹图谱研究(1)
[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,1.8 μm);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 mL·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。

[Abstruct]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.

羊耳菊Inulac appa(Buch.-Ham.exD.Don)DC.为菊科旋覆花属植物的新鲜或干燥全草[1],又名猪耳风、羊耳风、蜡毛香等,在我国分布较为广泛,云南、四川、贵州、江西、等地均有分布[2]。其性辛、微苦,具有疏风散热,解毒消肿之功能,常用于治疗感冒发热,咽喉肿痛等症状[3]。羊耳菊全草中主要含黄酮、酚类、倍半萜、有机酸和挥发油等成分[4]。目前已有的文献报道中多以羊耳菊药材的化学成分研究为主[5-7],而针对其质量控制的报道仅有单一成分、总黄酮及挥发油的含量测定[8-10],尚未见到对羊耳菊药材指纹图谱的研究报道。由于中药成分复杂,任何单一的活性成分或指标成分都难以有效地评价中药的真伪优劣[11]。因此本实验利用高效液相色谱法研究并建立了羊耳菊药材的指纹图谱,并对贵州不同产地的羊耳菊药材进行比对,以期进一步的完善羊耳菊药材的质量控制方法。
