title: [The analysis and identification of fritillaria cirrhosa by Raman spectra].
abstract: Laser Raman spectrum technology was used to distinguish fritillaria cirrhosa from its adulterants rapidly and accurately. The study is based on that different traditional Chinese medicine contains different chemical compositions, and the differences could be displayed in Raman spectra. The Raman spectra of fritillaria cirrhosas shows that several characteristic strong peaks could be found at 442, 480, 863, 941, 1 083, 1 129, 1 342, 1 463 and 2 910 cm(-1), and a few obvious peaks appear at 111, 302, 360, 409, 527, 579, 618, 718, 767, 1 052, 1 083, 1 207 and 1 261 cm(-1). According to the Raman spectra, a Raman fingerprint of fritillaria cirrhosa was set up, which could be used to distinguish its adulterants. This analysis could be used in identifying fritillaria cirrhosa rapidly, accurately and nondestructively.
