CHARACTERIZATION OF THREE AQUATIC ANGIOSPERMS FOR PHYTOCHEMICALS AND ANTIMICROBIAL ASSAY IN INDIA

The Most aquatic angiosperms possess phytochemical and antimicrobial properties.Phytochemical screening revealed the presence of biologically active substances (flavonoids, tannins, sterols, and resins) at various concentrations.For this purpose, we characterized three aquatic plants i.e.Nymphoides indica, Nymphoides hydrophilla and Hydrilla verticillata were examined to determine the presence of photochemical properties using standard methods and antimicrobial activity, as were studied against two bacteria i.e.Bacillus sp. and Brevundimonas sp., which were determined by the agar diffusion method.N. indica has been found to be biologically active with a few phytochemicals that have been recovered viz.saponin, starch, flavonoids, triterpenoids, steroids, glycosides, and tannins.In N. hydrophilla alkaloids and carbohydrates were recovered more than N. indica and triterpenoids were not found in N. hydrophilla likewise presence of starch, carbohydrate, tannin (aqueous extract), and flavonoids were found in H. verticillata.zone of inhibition was recorded 1.4 cm for Bacillus sp. by ethanol extraction, and H. verticillata and N. indica did not show any antimicrobial activity against either bacterial species i.e.Bacillus sp. and Brevundimona sp.Further research should be carried out to isolate potential antimicrobial agents from these extracts.These aquatic angiospermic plants can also be a source of biologically active compounds and can be helpful in pharmacognosy and modern drug production.
