Abstract
The macro and micromorphology of the stem and leaf of Tecoma argentea (Ber. & Schum) are presented to show the diagnostic characters of these organs by which they could be identified and differentiated in the entire and powdered forms. The lipid content is also studied using TLC techniques revealing the presence of b-sitosterol and a-amyrin.
From the methanolic extract of the leaves seven flavonoids were isolated. Their structures were established by physical, chemical and spectral methods, proved to be: luteolin, scutellarein, auercetin, 6-hydroxyluteolin-7-o-glucoside, chrysin-7-o-glucoside, scutellarein-7-o-rhamnoside and rutin.
