| Abstract:Objective：The electronic-tongue technology was used to analyze the bitterness of different sources of Gentianae Radix and its origin and quality. Methods：Through the determination of Gentianae Radix extract from different sources by electronic tongue，the taste of the sample was tested objectively. The quality and origin of Gentianae Radix medicinal materials were determined by the main component analysis（PCA）and discriminant factor analysis（DFA），and the results were verified by HPLC and microscopy. Results：The results of the determination of 10 batches of Gentianae Radix herbs were consistent with the results of high performance liquid chromatography. Conclusion：The technology of electronic-tongue can be used to identify the quality and variety of Gentianae Radix. |
