Pharmacognostical evaluation of aerial parts of Graptophyllum pictum (L.) Griff. (Syn: Justicia picta Linn.): A well-known folklore medicinal plant.
OBJECTIVE
Graptophyllum pictum (L.) Griff. (Family-Acanthaceae) occupies a key role in traditional system of medicine. Since an extensive literature survey did not provide any information about studies on its standardization. Therefore, we designed the current study to establish the quality control parameters of G. pictum aerial parts.


METHODS
The investigation included determination of various standardization parameters such as macroscopic and microscopic studies, physicochemical parameters as well as phytochemical analysis of the crude drug.


RESULTS
The microscopy study of aerial parts revealed that stem shows typical dicotyledonous characters with prismatic crystals of calcium oxalate in the cortical region and dorsiventral leaf. Physicochemical constants such as moisture content, ash values, fluorescence analysis, and extractive values were established. Preliminary phytochemical analysis confirmed the presence of alkaloids, flavonoids, saponins, tannins, etc.


CONCLUSIONS
The present study suggests establishing the parameters for pharmacopoeial standardization of G. pictum.
