ABSTRACT
The aim of this paper is to apply near infrared spectroscopy techniques to construct a rapid identification method for 8 kinds of mineral Chinese Medicines containing carbonates. The qualitative model using clustering analysis method in OPUS software can identify accurately 8 kinds of carbonate-containing mineral Chinese medicines. The near-infrared quantitative model was established by using partial least squares method (PLS) for 7 mineral Chinese Medicines in which main component is calcium carbonate. Compared with the results by EDTA titration, the established quantitative analysis model for calcium carbonate content showed a good prediction result that when the content is between 47.61% -99.17%, the average relative deviation of the prediction result is 0.24% and the average recovery rate was 100.3%. The results also showed that the model using near infrared spectroscopy can get not only a rapid identification of the 8 mineral Chinese medicines containing carbonates, but also an accurate and reliabe content determination of calcium carbonate for the 7 mineral Chinese medicines which contain the component.
