Digitized Pharmacognostical Study of Vicatia thibetica de Boiss and Its Similar Species
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 spe-cies,and carried out pharmacognostic studies and digital characterization of morphologic characteristics,character identification,mi-croscopic 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 estab-lished 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 be-tween 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 secre-tory tissues and the presence or absence of posterior inclusions,etc.CONCLUSION The established taxonomic checklists can effec-tively 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.
