Odor dominates more in the quality inspection of traditional Chinese herbal medicines. This paper focuses onwhat’s effect the electronic nose technology has played if applied in biopharmaceutical test based on odordiagnosis. There are some methods such as literature and data analysis, tests that are used for study. On thebasis of brief introduction to the electronic nose technology, the electronic nose PEN3 acquires the overallinformation of the volatile odor from the miscible Chinese herbal medicines of three typical families. Theeigenvalues extracted by the Principal Component Analysis (PCA) act as the input values for moderecognition method to test the three groups of miscible medicine materials. The results reveal that only theAmomum villosum in the training set samples is misjudged, the correct rate reaches 93.23%, and the rest areall 100%. It is suggested that the electronic nose technology can realize the test on miscible Chinese herbalmedicines, thus providing a new idea for testing the biopharmaceuticals.
