ABSTRACT
Aquatic plants are found in a wide range of flooded environments that differ from terrestrial ecosystems in their soil composition and water availability. Depending on their association with the water within these environments, aquatic plants can be classified into different categories, namely emergent, floating, submerged, and riparian. These different categories have been reported to differ in chemical composition due to their relationship with the external environment. Consequently, different types of aquatic plants are found in different continents of the world. The external environment exerts various types of biotic and abiotic stresses, which signals the plant to protect themselves through the production of phytochemicals. Certain isolated phytochemical classes have been reported to be phenomenal targets for treatments in a wide range of human ailments and can be included into pharmaceuticals and cosmetics as a more botanical or natural approach to healing.
