Pharmacognostical and Phytochemical Investigations on Tecoma Stans Flower

Establishment of pharmacognostic profile of the flowers of Tecoma stans will assist in standardization for quality, purity and sample identification. Evaluation of the fresh, powdered and anatomical sections of Tecoma stans flowers were carried out to determine macromorphological, micromorphological, physiochemical and phytochemical profiles. Pharmacognostical studies involve the anatomical sections and powder analysis of flower, physiochemical studies such as loss on drying, extractive values, ash values etc. were done. In phytochemical studies the flowers are extracted with different solvents and qualitative chemical tests for each extracts were performed only alkaloids are isolated and characterized in the other parts of this plant. From phytochemical screening of flower parts we can find out various other secondary metabolites and also characterization.
