The present study deals with pharmacognostic and phytochemical analysis of Acacia nilotica (Lam.) Willd. ex Del. of the family Mimosaceae. The various parts of this plant like leaves, stem bark, root and gum are used by the tribal people in traditional medicine for curing the different diseases such as diarrhoea, dysentery, diabetes, acidity, etc. The evaluation of quality and purity of crude drugs by means of various parameters is the most important aspect of pharmacognosy. The parameters like micromorphological, anatomical, physical constant and fluorescence analysis have been employed for the pharmacognostical evaluation of different parts of this plant. Microchemical and histochemical parameters are used for phytochemical screening. Leaves are amphistomatic and stomata are diacytic with few anaisocytic types. Stomatal index is 29.79 on the upper surface and 30.08 on the lower surface. Palisade ratio is 2.16. Non-glandular, unicellular with pointed apex trichomes are present on both surfaces. The T.S. of petiole is horse-shoe shaped in outline and 3 vascular bundles are present of which one larger, centrally located and two smaller vascular bundles are present in the periphery. Methanolic extracts of leaf indicate presence of tannins, proteins, flavonoids, steroids, etc. Ash value and moisture content of the leaves were found to be 09.17% and 67.09 % respectively. This study will provide some diagnostic features by which the crude drug of this plant can easily be identified.
