| Abstract: | Oroxylum indicum (Linn.)Vent. is one such plant which is extensively used in the
Indian systems of medicine as an important ingredient of “Dashmula” and in the
treatment of many diseases. Proper identification of the drug is desired for
obtaining its complete therapeutic effects. It is with this aspect in view the
present study dealing with pharmacognostical study and some other related
studies of the stem bark of the species O. indicum (Linn.)Vent. were
done. The stem bark is characterized by the well developed cork region;
phelloderm region consisting number of stone cells and fibres, ceratenchyma is
also present in inner phloem region, medullary rays are heterogenous and
multiseriate, minute starch grains up to 5 μm in diam. are present in secondary
phloem region. Powder of stem bark shown fragments of cork cells, stone cells
and sclereids, fragments of fibres, parenchymatous cells, filled with black
brown content, acicular crystals and starch grains were also found present. TLC
of various extracts showed spots in different solvent system and phytochemically
the plant was found to contain flavonoids, saponin, phenolic and tannins. |
