ABSTRACT

In this paper, the characteristics and differences of medicinal materials from different origin were analyzed and the origin was identified according to the data of mid-infrared spectrum. Firstly, data integration was carried out, which was divided into 11 producing areas according to data standards,and the mid-infrared spectrograms of medicinal materials[1] from different producing areas were drawn by MATLAB. According to this, it was found that the spectrograms of the same medicinal materials from different producing areas had small differences, and the absorbance of some producing areas was higher than that of others, and there were slight differences in the trend of waveform changes. Potential semantic analysis model was established to obtain similarity function and correlation calculation to obtain the result of origin identification.
