Pharmacognostic and preliminary phytochemical screening of leaves of Tecomaria capensis

Tecomaria Capensis belonging to thefamily Bignoniaceae is an evergreen climber with leaves which are opposite , slightly serrated, green to dark green, pinnate with 5to 9 oblong leaflets . The flowers are trumpet shaped with colour ranging from orange to orange-red to apricot.The present study aimed to explore the pharmacognostic and phytochemical screening of leaves of Tecomaria capensis. In the microscopic studies, the leaves showed the presence of trichomes, collenchyma, vascular bundles, spongy parenchyma, palisade cells and Anomocytic stomata. Phytochemical evaluation revealed the presence of alkaloids flavinoids, glycosides, proteins and steroids. Establishment of pharmacognostic profile of the leaves will assist in standardization for quality, purity and sample identification. The results of the study could be useful in setting some diagnostic indices for the identification and preparation of a monograph of the plant.
