摘　　要：Two non-destructive instrumental methods, infrared spectroscopy （IR） and X-ray diffraction （XRD）, were studied for qualiW evaluation of Lobelia chinensis Lour. （L chinensis）. We obtained the IR spectra and XRD patterns of L chinensis collected from different sources. The similarity of samples was analyzed by cal- culating the cosine coefficient. The cosine values were in the range of 0.83-0.90, indicating that the main components ofL chinensis samples are similar. Sample L1 and L6 showed a slightly lower similarity than that of L2, L3, L4, L5 detected by the two methods, which revealed that IR and XRD methods exhibited analogous detection ability for quality evaluation of L. chinensis. The two methods could be highly re- commended as simple and rapid detection means for quality evaluation of L. chinensis.Two non-destructive instrumental methods, infrared spectroscopy （IR） and X-ray diffraction （XRD）, were studied for qualiW evaluation of Lobelia chinensis Lour. （L chinensis）.
