[Objective] This study aimed to study the pharmacognostical properties of medicinal parts of stems and leaves of Viburnum Sargenti Koehne to provide refer- ence for its identification and application. [Method] Methods of characters and micro- scopic identification were used. [Result] Characters, transaction and microscopic characteristics of stems and leaves of V. sargenti Koehne were analyzed systemati- cally. [Conclusion] The experimental results can provide reference for the pharma- cognostical identification, further exploitation and utilization of stems and leaves of V. Sargenti Koehne. 展开更多
