Objective:
To perform a pharmacognostical study of the leaf of Uncaria hirsuta Havil.
Methods:
The specimens of Folium Uncariae Hirsutae were collected for studying its characteristics, microscopic appearance and thin-layer chromatography.
Results:
The leaf of Uncaria hirsuta Havil was characterized by numerous multicellular non-glandular hairs, 2 lines of palisade tissue, a diacytic type of stoma, and clustered crystals in its parenchyma. At least two kinds of alkaloids identical to the control were identified in the specimens.
Conclusion:
The results can be used as the evidence for identification, formulation of the quality-control standards as well as further utilization of Folium Uncariae Hirsutae.
