AB  - Pigmentary colours from ten ornamental horticulture flowering plants commonly found in Akure metropolis, Ondo State, Nigeria, were steeped extracted in various solvents and analyzed using UV-visible spectroscopy.  All  the  pigments  extracted  exhibited  strong  absorptions  in the visible region of the range 400-580 nm. Bougainvillea and Allamanda flowers manifested various hues in acidic and basic media, showing that they could be used as indicators in a titration where a change in pH equivalent of the environment is required such as acid-alkali titration.
