1. differentiate a method for legal Herba Ephedrae based near infrared spectrum, comprise the following steps:

  • (1) collection of Chinese ephedra sample and preparation;

    (2) near infrared spectrum of Chinese ephedra sample is gathered;

    (3) optimum spectrum pre-treating method is selected;

    (4) optimum modeling spectral range is selected;

    (5) calibration model differentiating legal Chinese ephedra is set up based on Chinese ephedra near infrared spectrum data;

    (6) evaluate the performance of positive model for school building;

    (7) by positive model for school building, the near infrared spectrum of acquisition and processing Chinese ephedra sample to be analyzed in the same way, differentiates whether it is legal Chinese ephedra.
