Abstract:
To establish seven kinds of minerals containing sulfate kind of near infrared spectral identification method
of traditional Chinese medicine (TCM). 7 species of mineral medicine containing sulfate after crushing sieving, measure all the samples in 12 000-4 000 cm-1 section within the scope of the near infrared spectrum, spectrum signal by different pretreatment methods, after the screening of the different characteristics of the spectrum to extract the effective information, using cluster analysis method for qualitative identification. In 8 600-8 100 cm-1, 5 843-4 245 cm-1, 7 096-6 337 cm -1 section within the scope of the atlas signal after the vector normalization and multiple scattering correction, K-average clustering analysis to 20 batches sulfate kind of mineral medicine is divided into seven categories, the results of the analysis method and the traditional traits identification results are basically identical. This method is simple, fast, and can be used for these minerals containing sulfate class the qualitative identification and quality control of Chinese traditional medicine.
