Phytopharmacogostical Studies on Root Bark of Oroxylum Indicum, Vent

The root bark of Oroxylum indicum, vent (Syonakh) belonging to family Bignoniaceae, are reported to have a great medicinal value. Pharmacognostical evaluation including examination of morphological and microscopical characters, determination of quality control parameters such as ash values, extractive values, moisture content, foreign matter, and microbial contamination were carried out. Phytochemical screening including qualitative chemical examinations was also carried out. Hence, the present attempt was undertaken to investigate the Phytopharmacognostical studies of root bark of Oroxylum indicum. The study revealed the presence of cork, cortex with stone cells and acicular crystals of calcium oxalate, phloem region associated with medullary rays, which contained phloem parenchyma and stone cells. Phytochemical screening of the plant showed the presence of phytoconstituents like flavonoids, alkaloids and anthraquinone.
