| Abstract: | Objective] The research aimed to establish an accurate method to identify the infrared spectrums of Microcos paniculata and Plumeria rubra.Method] Collecting the IR fingerprint of Microcos paniculata and Plumeria rubra samples by MIR,take the information of fingerprint region as observed variables,and then identify analysis them combining with principal component analysis.Result] According to the infrared spectrum information,we could obviously differentiate the Micmcos paniculata and Plumeria rubra by MIR fingerprinting combined with principal component analysis.Conclusion] MIR fingerprinting combined with principal component analysis is objective,accurate and fast,which could be used to identify the infrared spectrum of different Chinese medical herbs. |
