Abstract: The present research was carried out to investigate the Preliminary phytochemical screening, and physicochemical analysis of aqueous extracts bulb of Eulophia graminea. The phytochemical screening showed the presence of alkaloids, Flavonoids, Phenols, Terpenoids, Anthocyanidins, Saponins, Tannins and Glycosides in different extracts of bulb. Results of physicochemical analysis shows the percent of water soluble as 32.29 gm alcohol soluble ash 12.10 gm; whereas acid insoluble soluble ash 1.27gm the loss of weight on drying at found to be 6.29 gm. Qualitative analysis of phytoconstituents and physicochemical analysis of Eulophia graminea was not reported earlier and in other species Eulophia also not reported. Presence of bioactive constituents may exhibit various biological activities in support as represented in the herbal usage against vermifuge and as ear drops.
