Biochemical Assessment of Some Red Sea Brown Algae with Potential of Antioxidant and Antimicrobial Agents

The nutritional compositions of fatty acids (FAs), amino acids (AAs), polysaccharides, and phenolic compounds from brown seaweeds Cystoseira trinodis, Dictyota cervicornis, Padina gymnospora, and Turbinaria oranata were studied, and their antioxidant and antimicrobial activities were evaluated. For the assessment of phytocompounds, gas chromatography-mass spectrometry (GCMS) and high-resolution liquid chromatography (HPLC) were employed. D. cervicornis and T. oranata showed high levels of saturated FA in their lipophilic profiles (48.13 and 42.41
