Abstract:
OBJECTIVETo perform a pharmacognostical study of the leaf of Uncaria hirsuta Havil.
METHODSThe specimens of Folium Uncariae Hirsutae were collected for studying its characteristics, microscopic appearance and thin-layer chromatography.
RESULTSThe 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.
CONCLUSIONThe results can be used as the evidence for identification, formulation of the quality-control standards as well as further utilization of Folium Uncariae Hirsutae.
