Abstract：The FTIR spectra of flos lonicerae(FL) in four different areas are analysed by FTIR and the comparison of local(Henan) FL and FL in other areas is also studied. The result shows that the FL in different areas have the different content of main effective substance, so their absorption frequency and form in FTIR spectra are different as well. There is an obvious difference between Sichuan and local FL in wave number and form. Although FL in Shandong is famous as local herbs, their spectra are different slightly. The FL in Hebei and Shandong have almost the same spectrum. The local FL has a weak peak at 1 734 cm-1, however, the FL in Shandong and Hebei don’t have. The local FL has a group of weak peaks at 1 522 cm-1 and others have stronger and independent absorption or split peaks at the same point. The peak forms of local herbs are sharp from 1 155 to 1 045 cm-1 while those of Shandong and Hebei are flat and split ones. Therefore, FTIR can be not only a fast and reliable method to identify local herbs, but also a method to monitor the cultivating process and to purify and restore the Chinese medicine.
