A phytochemical screening of alkaloids, triterpenes saponins and tannin was carried out the selected medicinal plant parts of leaf, barks, rhizome and fruit samples from 63 plant species representing 26 genera and 25 families. The positive results of phytochemical diversity of bioactive constituents were alkaloids (58.73%), terpenoids (92.06%), flavonoids (90.48%), saponins (50.79) and tannins (31.74%) present in total of sixty three plant species.
