[Objectives] To establish infrared fingerprints of different parts of Boenninghausenia albiflora(Hook.) Reichb.ex Meissn. and Boenninghausenia sessilicarpa Levl.(two sources of Yi medicine Ebazema) and analyze the similarity between them. [Methods] The infrared fingerprints of powder of B. albiflora(Hook.) Reichb.ex Meissn. and B. sessilicarpa Levl. were measured, and the common peak rate and variation peak rate of six samples were calculated to establish the sequence analysis method of common peak rate. [Results] There was a very high common peak rate(≥81.3%) and a very low variation peak rate(≤15.4%) between S1 and S4 as well as S2 and S6. There was a low common peak rate between S1 and S3 as well as S3 and S4, and the common peak rate was 42.9% and 47.6% respectively. There was a low common peak rate(≤47.6%) and a high variation peak rate(≥100.0%) between S1 and S3 as well as S3 and S4. [Conclusions] The method is simple and convenient to operate, can quickly identify different parts used as medicine of B. albiflora(Hook.) Reichb.ex Meissn. and B. sessilicarpa Levl.(two sources of Yi medicine Ebazema), and provide a new method to judge whether the two are equivalent when being used as medicine and quality evaluation.
