Pharmacognostic And Preliminary Phytochemical Analysis Of Millingtonia Hortensis l. And Tecoma Stans L.

The present study deals with the determination of pharmacognostic features and phytochemical analysis of Millingtonia hortensis L. and Tecoma stans L. leaves belonging to the family Bignoniaceae. The phytochemical screening of ethanol, acetone, chloroform and water extracts shows the presence of carbohydrate, reducing sugar, protein, alkaloids, phenols, phytosterols and amino acid and absence of cardiac glycosides in all the extracts except chloroform extract. From this study it indicates that Millingtonia hortensis L and Tecoma stans L. have high source of secondary metabolites.
