摘　　要：目的建立细花滇紫草及其变种的红外指纹图谱,为其质量控制及科学评价提供科学依据。方法采用傅里叶变换红外光谱(FTIR)技术对产自西藏自治区不同地区的10批细花滇紫草的样品进行分析,建立细花滇紫草红外指纹图谱。结果细花滇紫草在831、1263、1375、1417、1514、1614cm-1处有明显的特征吸收峰,样品间相似度大于0.9,而与团花滇紫草的相似度小于0.75。结论红外指纹图谱可以作为细花滇紫草药材的快速鉴别方法及筛选优质药材的手段。Objective To establish the infrared（IR） fingerprint of Onosma hookeri and its variants for quality control and evaluation. Method 10 batches of O. hookeri from Tibet were analysised by Fourier transform infrared spectroscopy（FTIR） to establish the IR fingerprint of O. hookeri and its variants. Results The characteristic absorption peak of O. hookeri appear at 831, 1263, 1375, 1417, 1514, 1614 cm-1. The similarity between samples were greater than 0.9, but the similarity between O. hookeri and O. glomeratum was less than 0.75. Conclusion The infrared fingerprint can be used as a rapid method for identification and quality screening of O. hookeri.
