ABSTRACT
<p><b>OBJECTIVE</b>The spectral imaging method was used to quickly identify the Cortex Dictamni pieces and its counterfeit alangium Chinese, which is a potential method would be applied to control the quality of the Cortex Dictamni pieces.</p><p><b>METHOD</b>Standard sample, 5 cortex dictamni samples and its counterfeit alangium Chinese of different sources were tested by the liquid crystal imaging instrument. The spectrum resolution was 5 nm, the spectral range was from 405 nm to 680 nm, and the spatial resolution was 50 lp x mm(-1). The characteristic spectrum curves were picked up from spectral cube and principal analysis method was used to analyze the results.</p><p><b>RESULT</b>The identification results by the spectral imaging method accorded well with the results by the traditional biology and chemistry analysis method.</p><p><b>CONCLUSION</b>The spectral imaging analysis method can be used to identify the cortex dictamni pieces and its counterfeit alangium Chinense. The testing course is convenient, quick and noninvasive.</p>
