ABSTRACT

Hydrophytes (aquatic plants) are important constituent of the aquatic ecosystem. They have a significant role in the life where they could be used as shelter, food, medicine, biofilters, and for other purposes. However, indigenous information for potential utilization of aquatic plants is lacking. In this study, four cosmopolitan aquatic plants in the Nile River, Aswan district, Egypt were manipulated for their ecological and bioactivity potentials. These plants are Polygonum senegalensis, Ceratophyllum demersum, Potamogeton crispus and Potamogeton perfoliatus. These hydrophytes are widely distributed in different non-polluted and polluted sites in Aswan district.They are of ecological potential as effective bio-filters for a variety of pollutants as manipulated in the present study. The bioactive potentials of these hydrophytes, e.g., antioxidant, antimicrobial, antitumor and other activities are shown.
