With the development of science and technology, modern scientific identification technology has gradually been applied to the origin and quality identification of Chinese herbal medicines. For example, the use of Baosheng CNOSE electronic nose and other instruments and equipment to analyze the smell and other aspects of Chinese herbal medicines, so as to identify the origin and quality of Chinese herbal medicines, these modern scientific and technological identification methods are more accurate and fast, and can effectively ensure the quality and safety of Chinese herbal medicines. To sum up, the identification of the origin and quality of Chinese herbal medicines can be achieved by various methods such as appearance and odor identification, physical and chemical property testing, fingerprint analysis of medicinal materials, and modern scientific and technological identification methods. However, when making identification, we need to pay attention to choosing the appropriate method and combining multiple means to make a comprehensive judgment to ensure the accuracy and reliability of the results. Only through scientific methods and means can we truly identify the origin and quality of Chinese herbal medicines, and provide guarantee for the safety of drug use for the majority of consumers
Shanghai Baosheng CNOSE electronic nose electronic nose is an odor analysis instrument, also known as artificial olfactory system, which is developed on the basis of material science and sensing technology, using the biomimetic technology of various sensors, imitating the working mode of human olfactory cells, and realizing the detection of gases and odors. Due to the influence of multiple variables such as different origins, different varieties, different growth environments, different harvest periods, and different processing conditions, the overall odor of Chinese herbal medicines will be different, and the sensors of the electronic nose will show different responses to different odors, so as to achieve the purpose of differentiation and identification. The wisdom nose is composed of the most advanced foreign sensors, and it is the electronic nose with the best stability and the highest detection accuracy of similar instruments. Ideal for the detection of liquid and solid samples containing volatile substances. The standardization and scientific research of the quality of traditional Chinese medicine has always been a hot topic in the field of traditional Chinese medicine. Under the guidance of traditional Chinese medicine theory, the smell of Chinese herbal medicines is regarded as one of the important criteria for the identification of variety, origin and quality. Most Chinese medicinal materials have their own special smells, such as: musk is named because of the aroma of distant radiation, and the soybean grass and stinky sycamore are named because of the special smell, through these smells, people can distinguish different Chinese herbal medicines. 
The application of CNEX electronic nose in the field of traditional Chinese medicine includes: 1. The quality control of Chinese herbal medicines includes the establishment of odor fingerprints of Chinese herbal medicines, the study of the harvest period of Chinese herbal medicines, the identification of the origin of Chinese herbal medicines, and the identification of the growth environment of Chinese herbal medicines. 2. Evaluation of the processing process of Chinese herbal medicines, 3. Evaluation of the quality of Chinese patent medicines and their intermediates, 4. Evaluation of the odor masking effect of Chinese medicines, 5. Auxiliary research and development of placebo of Chinese medicines.
