Algae are aquatic plants that contain bioactive compounds with medicinal properties. These compounds, including pigments, polysaccharides, polyphenols, terpenoids, and fatty acids, have been shown to exhibit antioxidant, anti-inflammatory, antitumor, and antiviral activities. The exploration of these compounds has shown promise in the prevention and treatment of chronic diseases, including cancer, cardiovascular diseases, and viral infections. However, traditional extraction methods can be time-consuming and may require the use of toxic solvents, resulting in environmental pollution. Advances in green extraction methods offer hope for the development of more sustainable and efficient methods to produce algae-derived compounds with medicinal values.
