| Abstract: | A new method for identifying Dipsacus Asperoides from different areas by near-infrared reflectance spectroscopy(NIRS) is established.The NIRS spectra processing by the multiplicative scatter correction(MSC) and second derivative(SD),are used to establish partial least square-discriminant analysis(PLSDA) model.The method can identify Dipsacus asperoides from different areas.This method can be used for the rapidly and accurately identifying Dipsacus Asperoides from different areas. |
