[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<sup>-1</sup>; 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.為菊科旋覆花屬植物的新鮮或干燥全草<sup>[1]</sup>,又名豬耳風(fēng)、羊耳風(fēng)、蠟毛香等,在我國分布較為廣泛,云南、四川、貴州、江西、等地均有分布<sup>[2]</sup>。其性辛、微苦,具有疏風(fēng)散熱,解毒消腫之功能,常用于治療感冒發(fā)熱,咽喉腫痛等癥狀<sup>[3]</sup>。羊耳菊全草中主要含黃酮、酚類、倍半萜、有機(jī)酸和揮發(fā)油等成分<sup>[4]</sup>。目前已有的文獻(xiàn)報道中多以羊耳菊藥材的化學(xué)成分研究為主<sup>[5-7]</sup>,而針對其質(zhì)量控制的報道僅有單一成分、總黃酮及揮發(fā)油的含量測定<sup>[8-10]</sup>,尚未見到對羊耳菊藥材指紋圖譜的研究報道。由于中藥成分復(fù)雜,任何單一的活性成分或指標(biāo)成分都難以有效地評價中藥的真?zhèn)蝺?yōu)劣<sup>[11]</sup>。因此本實(shí)驗(yàn)利用高效液相色譜法研究并建立了羊耳菊藥材的指紋圖譜,并對貴州不同產(chǎn)地的羊耳菊藥材進(jìn)行比對,以期進(jìn)一步的完善羊耳菊藥材的質(zhì)量控制方法。
