| Abstract: | Objective： To appraise rationally the quality between wild and cultivated Radix A ngelica Sinensis. Methods： Evaporability composition of Radix Angelica Sinensis was sampled from headspace of emanating, and then response values were obtained. Principal component analysis （PCA） and discriminant factor analysis （DFA） were used to combine the optimum feature parameters. Results： The odor of wild Radix Angelica Sinensis was different from that of the cultivated. Coneluion： Electronic nose technology to distinguish Radix Angelica Sinensis odor is consistent with traditional experience discrimination. Electronic nose.combined with PCA and DFA canbe applied to identify the quality of traditional Chinese medicine. |
