[Pharmacognostic studies on Desmodium gyrans].
OBJECTIVE
To study the characteristic features of Desmodium gyrans in order to provide a basis for rational exploitation and utilization of the herb.


METHODS
Samples of the title plant were collected, the microscopic features of cross sections and powders were studied. TLC profiles and UV absorption of the plant extract were examined.


RESULTS
Calcium oxalate crystals were found in cells of transverse sections. Nonglandular hairs were observed on leaf surfaces. Characteristic peaks in the UV spectrum were identified.


CONCLUSIONS
The distinct characteristic features revealed in this studies can serve as evidence for the identification of D. gyrans.
