ABSTRACT: Five kinds of traditional flower Chinese
medicine powders (TFCMD) were identified
using tuneable liquid spectral imaging
instrument, to discuss the application range and advantages of spectral imaging
technology in Chinese medicine identification and analysis field. The testing system is the liquid crystal
multispectral imaging system designed by ourselves. All the tests are standard
samples supplied by National Institute for Drug Control. The
spectral cubes of Campsis grandiflora, Carthamus tinctorius, Albizzia
julibrissin, Dendranthema morifolium, and Dendranthema indicum were
captured, and then the
normalized characteristic spectral curves of them were picked up. The spectral
resolution is 5 nm, and the spectral
range is 400 nm - 650 nm. The result shows that different
TFCMD has
different normalized characteristic
fluorescence spectral curve. Spectral imaging technology can be used to identify TFCMD, and the testing course is
convenient, quick, noninvasive and without pre-treatment.
