In the range of 800~1800 cm-1, the second-derivative spectra and two-dimensional correlation spectra effectively distinguished different Formula Granules, between which the latter was superior. Conclusion By comprehensively comparing the FT-IR and corresponding second derivative spectra and two-dimensional correlation spectra, identification for 3 Formula Granules of Ginseng, Red Ginseng and American Ginseng could be realized rapidly and accurately."/>
