| Abstract: | OBJECTIVE A rapid identification model of Peucedani Radix and its adulterants was developed by near-infrared spectroscopy with chemometrics methods. METHODS eighty-nine samples including Peucedani Radix samples from 6 main origin areas(54 samples) and 7 common adulterants(35 samples) were collected. Near-infrared spectrums were collected. The identification model of Peucedani Radix and its adulterants was established by chemometrics methods. RESULTS The optimized model parameters were as follows:the spectrum preprocessing method was multiplicative signal correction+first derivative+norris derivatie filter, the spectrum band was 6 800-5 700 cm-1, and the principal component number of PLS-DA modeling method was 14. The identification result of the validation sets showed that the correct recognition rate of the authenticity identification model was 100%. CONCLUSION This approach of near-infrared spectroscopy is simple and rapid. It can correctly identify Peucedani Radix and its adulterants, and providing a new method for rapid qualitative evaluation of Peucedani Radix. |
