Abstract:

Objective: To perform pharmacognostic studies for Wupicao(Potentilla kleiniana). Methods: Source identification,
character identification, microscopic identification, as well as physical and chemical identification were used. Results: Wupicao was
the dry complete grass or the whole plant of Rosaceae Potentilla kleiniana Wight et Arn. Crude drug identification was described in
detail. Conclusion: The study could provide a theoretical basis for identification of its pharmacognosic identification, formulation of
quality standards and further development and utilization.

Key words: Wupicao, Potentilla kleiniana Wight et Arn, pharmacognostic studies
