Abstract：The Pericarpium Citri Reticulatae from different years were analyzed and identified by Fourier Transform Infrared Spectroscopy (FTIR) and method of relative coefficience compare in this paper. The evidence indicated that the main constituent of the alcoholic extract of Pericarpium Citri Reticulatae was hesperidin，the FTIR spectra of the alcoholic extract of Pericarpium Citri Reticulatae ranged among 2 851, 1 716 and 1 516 cm-1,and the peak had the obvious tendency to increase while the times prolonged, moreover its second derivative spectra also made corresponding changes among 1 734, 1 517 and 1 276 cm-1. Compared to the alcoholic extract of Pericarpium Citri Reticulatae in 1 year，their relative coefficience decreased gradually when the years increased. According to the fingerprint character of the alcoholic extract of Pericarpium Citri Reticulatae, it meant that accomplished with the time extended, the hesperidin was increasing, meanwhile, some organic acid and ester were increasing too. Above all, it was proved that FTIR was a fast and simple method to identify the Pericarpium Citri Reticulatae in different years.
