The anatomical, pharmacognostical and preliminary phytochemical studies of leaf and flower powder mixture of Stereospermum chelonoides were studied to understand the quality of botanical raw materials used in health industry. Morphological features, microscopic characters and physiochemical features like total ash, acid insoluble ash, water soluble ash, organic solvent extractives, phytochemical nature of the powder and extracts, fluorescence nature of the powder and microbial limit assay were performed using standard textual methods. The morphological, microscopical features and microbial nature were within the limits of ayurvedic pharmacopeia of India. Extracts and powder showed the presence of terpenoids, flavonoids, Saponins, phenolic compounds and carbohydrates. These observations would be of immense value in the botanical identification and standardization of drugs in a crude form.
