• [Display omitted] •Electrochemical activity profile of herbal medicinal materials shows a unique fingerprint related to the species.•Introduction of graphene can enhance electrochemical fingerprint signals.•The authenticity of the herbal medicinal materials can be identified by several patterns and color recognition modes.•This methodology can be used for dry sample as well as post-treated sample.•This methodology could be further extended for food quality control. A quick and low-cost method for traditional medical herbs identification is essential for the plant resources and pharmaceutical industries. The electrochemical voltammetric profile of plant tissues can be considered as a unique fingerprint available for herbal traditional medical herbs identification. In this work, a chip-based portable method is proposed for measuring the electrochemical fingerprint of a series of medicinal herbs with the assistance of graphene. Fingerprints were converted into patterns, colors and pixels for easy identification. The results indicated that the proposed electrochemical fingerprint sensor can recognize medicinal herbs in fresh, dried and prepared forms. In addition, the taxonomic relationships of these species were studied based on the recorded fingerprints, since the degree of differences in electroactive compounds can reflect genetic differences. The results indicate that the electrochemical fingerprints recorded from fresh samples can effectively reflect the phylogenetic position of species.
