[A novel analyzer of traditional Chinese medicines fingerprint].

The chromatographic fingerprint of traditional Chinese medicine is a way of comprehensive expression to show its complicated chemical composition. It is a generally-accepted method for analyzing the quality of traditional Chinese medicines. In this article, we address an analysis algorithm of traditional Chinese medicines fingerprint and its FPGA circuit method. With the use of a method based on combined GA training BP-NN, and by virtue of high-speed operation and parallel computing, the system is implemented successfully with FPGA which can be used in field control. The result shows that this is an efficient and superior method for use in the process of preparing raw Chinese medicines.
