Identification of Codonopsis Radix from different origins based on odor information
Provisionally accepted- Beijing University of Chinese Medicine, Beijing, China
Codonopsis Radix, a natural plant with edible and medicinal functions, is in high demand and cultivated in different regions. The place of origin affects the quality. However, environmental factors such as soil, climate, and altitude all have an impact on its quality. Therefore, identification of geographical origins of Codonopsis Radix is very important. This study used HPLC fingerprint and E-nose technology to identify the origin information of Codonopsis Radix. HPLC fingerprints can fully reflect characteristics of chemical components in Codonopsis Radix and provide a reliable chemical basis for identification of origins, while Enose technology captures and analyzes volatile odor of Codonopsis Radix by simulating human olfactory system, which realizes rapid identification of origin information. In order to reveal origin of special aroma of Codonopsis Radix in a deeper way, we further employed the SPME-GC-MS technique to elucidate the volatile substances of unique aroma. The results showed that Hexanal might be a key volatile compound in Codonopsis Radix from different geographical origins. This research indicated that Codonopsis Radix from different origins can be identified by odor information, which not only enriched index system for quality evaluation of Codonopsis Radix, but also provided new ideas and methods for origin identification of same type of plants.
