[Application of fingerprint analysis and computer pattern interpretation in identification and quality evaluation of traditional Chinese medicines].

The fingerprint analysis technique used in the quality control of TCM through identifying charactreristics and evaluating stability is set up with the rapid development of instrument analyses and computer pattern interpretation. There are many kinds of methods for establishment of fingerpirnt of TCM mainly including chromatography, spectroscopic method, x-ray diffraction and molecular biological technique. The methods of computer pattern interpretation in fingerprint of TCM includes fuzzy information analysis, artificial neural networks and gray relational grade cluster.
