Aqueous, petroleum ether, chloroform, ethanol and acetone extracts of the flowers were prepared by adding 50 g of fresh fallen flowers of the family Bignoniaceae (Jacaranda mimosifolia D. Don, Markhamia lutea (Benth.) K. Schum., Millingtonia hortensis Linn., Spathodea campanulata Beauv., Tabebuia rosea (Bertol.) DC. and Tecomaria capensis(Thunb.), Tecoma stans (L.) Kunth) to 200 ml of these solvents; the constituents were shaken at room temperature for 24 h. After incubation, the extracts were

Preliminary phytochemical screening was carried out according to the standard methods. The present study screened the phytochemical properties of seven ornamental flowers with thirty five 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. From these results, it can be concluded that the seven ornamental flower extracts may be used as broad-spectrum bioactive agents after extensive investigation.
