 Abstract : Ethanol and aqueous extracts of the flowers and the leaves were prepared by adding 50 g of sun dried leaves and fresh fallen flowers of the family Bignoniaceae {Jacaranda mitnosifolia D. Don, Tecoma stans (L) Kunth, Spathodea campanulata Beauv., Kigelia africana (Lam) Benth, Bignonia capreolata L.) to 200 ml of these solvents; the constituents were shaken at room temperature for 36 hours. After incubation, the extracts were filtered using Whatmann No. I filter paper, collected and stored. Preliminary phytochemical screening was carried out according to the standard methods. The present study screened the phytochemical properties of five ornamental flowers and leaves with twenty extracts and showed varied degree of phyto-constituents present. The presence or absence of the phyto-constituents depended upon the solvent used and physiological property of the flowers and the leaves. From these results, it can be concluded that the five ornamental flower and leaf extracts may be used as broad-spectrum bioactive agents after extensive investigation.
