Abstract:Identification method of forsythia suspense from 5 different habitats by near infrared spectroscopy coupled with pattern recognition based on SIMCA was proposed in this paper.In the spectra region between 6700cm-1 and 5300cm-1,5 predictive models of Lushi,Luanchuan,Luoning,Xin′an in Henan province,and Anzhe in Shanxi province were built separately by the standard normal variate (SNV) preprocessing method with SIMCA pattern recognition method,optimal principal components were 3,2,2,3,4.Under the α=5% significance level,1 sample wasn′t identified correctly in 10 prediction sample,it prove that method was established can identify exactly forsythia suspense from different habitats.
