In this study chemical composition (ash, protein, fiber, fat and carbohydrates) and mineral contents (Na, Ca, K, Fe, Mn, Mg, Zn, Cu, Co, Se and P) of Padina boergesenii collected from the Persian Gulf in the winter of 1389 and spring of 1390 have studied. Results indicate that the nutritional value of brown algae Padina boergesenii was 114.37 kilo calories in the spring and 154.208 kilo calories in the winter. Chemical analysis of the brown alga Padina boergesenii indicated these amounts of Protein, ash, carbohydrates, fat and fiber: (%12.26 ± 0.015), (%13.28 ± 0.01), (%25.97 ± 5.634), (%0.14 ± 0.036) and (%4.67 ± 0.709) DW in the spring and (%12.63 ± 0.042), (11.14 ± 0.01), (%15.24 ± 0.649), (%0.32 ± 0.032) and (%3.8 ± 0.112) DW in the winter, respectively. Difference between the means of protein, fat, ash and carbohydrates in spring and winter is meaningful (P ≤ 0.05); difference between the means of fiber in mentioned seasons is (P ≥ 0.05). Analysis of mineral contents of brown algae Padina boergesenii indicates these amounts for Fe, Ca, Na, K, Mg, Se were (1160.333 ± 19.85), (7554 ± 29.799), (10874.74 ± 1646.958), (10594.6 ± 692.67), (5569.33 ± 11.015) and (572 ± 9) ppm in the spring respectively also these values in the winter are (2265.667 ± 224.5982), (7820.93 ± 60.9008), (8728 ± 1032.42), (4612.97 ± 609.99), (6805.33 ± 154.212) and (526 ± 14.047) ppm respectively, therefore, it can be said that Potassium, Sodium and Selenium have higher amounts in the spring and difference between the means of potassium, iron, calcium, magnesium, selenium is meaningful in the brown algae Padina boergesenii (P ≤ 0.05); difference between the means of sodium is meaningless (P ≥ 0.05). Reference made to the results of this study regarding chemical and mineral composition specially Protein percentage and amounts of Selenium, Calcium, Potassium, Padina boergesenii is a recommended candidate as food supplement.
