Common and variation peak rates were calculated as dual-index for drug samples based on the infrared spectrogram of Angelicae Pubescentis Radix samples from different places. The results indicated that the common peak rates of 4 samples from Sichuan province, 2 samples from Gansu province, and 2 samples from Hubei province were higher than 73% , 79. 5% and 76. 3%, respectively. Also, the variation peak rates of 2 samples from Gansu province were lower than 12. 9%. Therefore, there is similar germplasm resources and similar chemical composition in the samples originated from the same place. However, for the samples originated from different places, their germplasm resources and chemical composition maybe have been changed. Fourier transform infrared spectrometry could be used to evaluate the rule of the fingerprint and overview of Angelicae Pubescentis Radix originated from different places by its changes of germplasm resources and chemical composition.
