Key Points

The study identified important pharmacognostic features of A. leiocarpus that assist in correct taxonomic identification.
Microscopic examinations revealed unique structures in the leaves, including stomata and starch grains.
Phytochemical screening demonstrated the presence of numerous phytochemicals in both the leaves and stem bark.
Findings may help prevent adulteration of products derived from A. leiocarpus, supporting traditional uses in medicine.

Abstract

Background calcium carbonate was absent. Physicochemical parameters, namely, moisture content (5.98%±0.23), total ash (7.50%±0.54), acid-insoluble ash (1.34%±0.82), water-soluble ash (2.60%±0.65), alcohol (9.40%±0.85) and water extractive values (6.50%±0.33) were also determined. Phytochemical test and TLC revealed the presence of numerous phytochemicals in the leaves and stem bark of the plant. Conclusion: The study showed A. leiocarpus stembark contains important pharmacognostic features that can be used as fingerprints for the correct taxonomic identification and description of the plants. The findings from this study will also help to check adulteration of products from the plant.
