Objective: To identify fastly and accurately in Curcumae Radix of multiple sources by electronic nose. Method: The detective parameters of the samples and metal sensors were selected by detector response values and the characteristic datum were used for statistical analysis through principal component analysis and discrimental factor analysis. Result: The electronic nose detection method of Curcumae Radix were established and the odor identification fingerprint of Curcumae Radix were obtained. Conclusion: The method was used for identifying Curcumae Radix of multiple sources by electronic nose to provide a new idea for the identification of traditional Chinese medicine of multiple sources.
