Evaluation of chemical components and physicochemical properties of two green macroalgae species Ulva intestinalis and Ulva linza from Persian Gulf

Nutritional, pharmaceutical, and healthcare properties of macroalgae are the most investigated subjects in macroalgae. In this study, nutritional and physicochemical properties of two important green macroalgae, Ulva intestinalis and Ulva linza, collected from the Persian Gulf, were investigated. In all analyses, we followed the reference methods with some modification. Results revealed that U. intestinalis contained higher protein content (15.79%) as compared with U. linza (9.90%) while U. linza had higher content of lipid (2.30%), ash (26.66%), phenol (2.16 mgGA/g) and flavonoid (11.7 mgQE/g) as compared with U. intestinalis with 1.98% lipid 22.50% ash, 1.02 mgGA/g phenol and 8.2 mgQE/g flavonoid. The two species did not show any significant differences about all analyzed compositions (P
