OBJECTIVE: To review the application of the pattern recognition to quality assessment of the Chinese Traditional Medicine. METHOD: Papers of application of chemical pattern recognition, pattern recognition of stereoscopic features and artificial neural networks to quality assessment of the Chinese Traditional Medicine were collected and the application of different method was reviewed. RESULT: IR, UV, GC, GC-Mass and the sum mass spectra were used to evaluate the chemical character of different samples, and the microscopic features of the epidermis were scored quantitatively by stereology and image analysis on the basis of classical taxonomy,. BP networks were also widely used. CONCLUSION: Chemical pattern recognition, pattern recognition of stereoscopic features and artificial neural networks are of important use in quality assessment of material medica.
