ABSTRACT

India cherishes a vast diversity of medicinal plants harboring from Himalayan Ranges to Cape Comarin. Among these medicinal plants Bougainvillea glabra is a specialized drought resistant medicinal and ornamental climber due to its robustness against arid climates. The present study was carried out to investigate the biochemical and phytochemical constituents of Bougainvillea glabra plant extracts qualitatively. A fresh, healthy twig of the plant was carefully collected from forest areas of Melagiri Hills, Dharmapuri district and was identified. The leaves were air dried; powdered and dry weight was measured. The methanolic extracts of dried leaves were prepared and analyzed for the presence of biochemical and phytochemical constituents. The silver nanoparticles were synthesized and pharmacognostic assay were performed. The results revealed the presence of carbohydrates, proteins and amino acids. The tests for phytochemical investigations indicated the presence of alkaloids, flavonoids, phenolic compounds, glycosides, phytosterols and saponins. The present study confirmed the presence of bioactive compounds through FTIR analysis and showed a broad range of antimicrobial activity. The study suggests that the qualitative presence of both biochemical and phytochemical substances will render a most promising facet for the development of new plant derived nanoparticles against pathogenic microbes.
