Estimation and comparison of effective compounds (mineral contents, amino acids compositions, fatty acids distributions, protein, fat and total fiber contents) in two algae species Sirophysalis trinodis and Polycladia myrica collected from Qeshm Island were done. The samples washed up with tap water and then were dried in an oven at 40 ◦C for 3 days. The dried algae samples were pulverized and packed in airtight plastic bags. The results showed that the marine macro-algae included low lipid contents about 0.03±0.01 % and 0.33±0.10% dry sample weight and proved to be a rich source of fatty acids (Palmitic and Oleic acid) and minerals. The protein content of these brown algae was lower than 15%. All essential amino acids were detected in the algae species, featured uniquely high concentrations of amino acids when compared to ground plants. Also, results showed that the chlorophyll amount dependent on solvent type and cell wall structure of algae. Hence, in this study, among the three solvents of acetone, diethyl ether and methanol, acetone showed the best performance for the extraction of chlorophyll in both algae S. trinodis and P. myrica. In general, the aim of this study was to determine the valuable compounds of two abundant species of brown algae in the south of the country and introduce them to food units. |
