Abstract
The brown seaweed Hormophysa cuneiformis (H. cuneiformis) is recognized as one of the most significant algal species along the Egyptian Red Sea coast and is considered as a promising source of bioactive compounds. This experiment evaluated the chemical components and scaving activity of three different extracts of H. cuneiformis (ethanolic, acidified ethanolic, and aqueous) collected from the Red Sea coast in Hurghada, Egypt. The reducing power, DPPH radical scavenging assay, total flavonoid content, total antioxidant capacity, and total polyphenol content are connotations of the antioxidant properties of H. cuneiformis. Additionally, nutritional analysis showed that H. cuneiformis is rich in fiber (34.24%), ash (30.93%), carbohydrates (28.5%), and proteins (5.24%), with low lipid content (1.09%) on an air-dry weight basis. In conclusion, the acidified ethanolic extract recorded the highest value of DPPH radical scavenging activity compared with the ethanolic and aqueous extracts. In addition, the flavonoid and total phenolic values were recorded the highest value in the acidified ethanolic and ethanolic extracts compared to other extract. Finally, we inferred that the acidified ethanolic extract had superior total antioxidant capacity and reducing power compared with the other extracts.
