Abstract(RBIP-178)

Objective: The objective of this work is to study about the macroscopic and microscopic characters, physico chemical evaluation and preliminary phytochemical studies of the bark of plant Plumeria alba Linn. Plumeria alba Linn. (Apocynaceae) commonly called White Champa, a small laticiferous tree or shrub, native to tropical America. It is 4.5m high, occasionally grown for its ornamental and fragrant flowers. The fruit is edible, latex is applied to ulcers, herpes and scabies and seeds possess haemostatic properties. Moreover its bark is bruised and applied as plaster over hard tumors.

Results: The powder of bark was found to be brown in color with slight bitter taste and odorless. On microscopically examination, the powder showed sclerenchyma, parenchyma cells, phloem fibers, starch grains and cork cells. Different parameters i.e. Total ash, acid insoluble ash, water soluble ash, loss on drying and swelling index were found to be 6.0, 2.3, 1.8, 1.33 and 20.0 respectively. The hot water soluble extractive was high in the bark of Plumeria alba. Preliminary phytochemical screening reveals the presence of Alkaloids, Carbohydrates, Flavanoids, Phenolic compounds, and Tannins in this plant.

Conclusion: Hence it can be concluded that the Plumeria alba bark has the appropriate pharmacognostical features and the presence of different chemical constituents makes it useful for further pharmacological studies and its use for human welfare.
