Abstract
The phytochemical screening of the powdered leaves and the stem bark of Anthocleista vogelii revealed the presence of carbohydrates, saponins, flavonoids, terpenes, sterols and phenols. Alkaloid was present in the leaves only. Moisture content, total ash value, acid-insoluble ash, water-soluble ash values and extractive values were also determined. Thin layer chromatography (TLC) analyses revealed seven spots for the leaf while the stem-bark revealed three spots using normal phase plates. The microscopic analysis of the upper and lower surfaces of the leaf revealed the presence of polygonal epidermal cells. The stomata distribution in the upper surface of the epidermis is more than that of the lower surface. The transverse section of the leaf indicated the presence of two layers of palisade cells, peculiar lignified astrosclereids scattered in the mesophyll. The transverse section of the stem bark showed diagnostic features such as the presence of astrosclereids, brachysclereids, macrosclereids, 3 or 4 layers of cork cells and medullary rays. The chemo microscopic analysis of the leaf and stem bark revealed the presence of lignin, cutin and oil globules. The result of this study revealed the chemical constituents and pharmacognostic profile of the plant. These are required in the preparation of a monograph in the plant. Key words: Anthocleista vogelli, pharmacognosy, medicinal plants.
