OBJECTIVE To establish a method for the pharmacognostic identification and digital characterization of the Vicatia thibetica de Boiss and its similar species. METHODS The original plant specimens of Vicatia thibetica de Boiss. and its similar species, and carried out pharmacognostic studies and digital characterization of morphologic characteristics, character identification, microscopic identification using digital camera, body microscope, light microscope, and digital imaging systems were collected and made. RESULTS Taxonomic checklists of morphologic characteristics, character identification and microscopic identification were established for the Vicatia thibetica de Boiss and 7 similar varieties [Sphallerocarpus gracilis (Bess.) K.-Pol., Pleurospermum hookeri var. thomsonii C. B. Clarke, Angelica acutiloba (Sieb. et Zucc.) Kitagawa, Pleurospermum franchetianum Hemsl., Ligusticum daucoides (Franch.) Franch., Heracleum millefolium Diels, Anthriscus sylvestris (L) Hoffm.], and it was found that the main differences between the 8 plants were in the flowers and fruits, and that the main differences in character identification were in the characteristics of the root heads, surfaces, and cross-sections, and that the main differences in the microscopic identifications were in the types of secretory tissues and the presence or absence of posterior inclusions, etc. CONCLUSION The established taxonomic checklists can effectively identify Vicatia thibetica de Boiss and its similar species, and provide a scientific basis for its species classification and clinical use. It also lays a foundation for the exploration of the application of intelligent identification technology in the identification of Tibetan medicines, and provides information for the platform of digital specimens of traditional Chinese medicine.
