Pharmacognostical characterization of leaves of Jasminum elongatum (P.J.Bergius) Willd. for quality control assessment

Sabeena Hussain Syed


Background: Jasminum elongatum belonging to the family Oleaceae have been used widely in ethnomedicinal practices for its medicinal value. However, no published work is available till date on pharmacognostical characterization. Objective: The objective of the study was to conduct pharmacognostical and phytochemical study of leaves of J. elongatum. Materials and Methods: Evaluation of leaf samples was performed by determining morphological, microscopical characters, physicochemical, and phytochemical analysis recommended by the World Health Organization. Results: Morphologically, the leaves are opposite with ovate to lanceolate in shape and acute apex. Microscopically, the epidermal region shows the presence of glandular and covering trichomes along with anomocytic stomata. The midrib region consists of horseshoe-shaped vascular bundles with spiral-shaped xylem vessels. Powder microscopy revealed the presence of spiral-shaped xylem vessels, spindle-shaped fibers, and stone cells. Physicochemical analysis and phytochemical analysis resulted a valuable data to establish standards for the plant. Conclusion: The establishment of pharmacognostical parameters of leaf material will be useful in identification and standardization of J. elongatum in obtaining quality formulations.
