Abstract:

Background: The objective of the research was to examine the pharmacognostic and phytochemical characteristics of Azadirachta Indica stem bark.
Materials and Methods: The study includes Macroscopic, Microscopic, Powder study, Histochemical, Preliminary Phytochemical and Physicochemical evaluation of stem bark of Azadirachta Indica.
Results and Discussion: The transverse section revealed 18-25 brown colored tangentially elongated and thick-walled cork cells. The cortex region shows 2-3 layers of collenchymatous cell followed by 15-20 rows of thin-walled parenchymatous cell. Lignified pericyclic region. Phloem region contains phloem parenchyma with clusters and prismatic crystals of calcium oxalate and tannins with transversely arranged tri or penta serrate medullary. Powder microscopic analysis showed the presence of suberized thin-walled cork cells, cortical parenchymatous cell and phloem parenchymatous cell with starch grains, parenchyma cells containing prismatic crystals of calcium oxalate. Physico chemical analysis was done by the parameters mentioned in Ayurveda Pharmacopeia of India.
Conclusion: Pharmacognostic and phytochemical evaluation can be used as a tool for identifying and confirming the authenticity and quality of Azadirachta Indica stem bark. This study helps to provide diagnostic tool for identification of stem bark of Azadirachta Indica.
