Identification and characterization of bioactive compounds in two algae species of Haematococcus pulvialis and Dunatiella saline from the waterbodies of Basrah region, Iraq

This study was conducted to identify and characterize bioactive compounds in two algae Chlorophyta species of Haematococcus pulvialis and Dunatiella saline collected from water bodies in the Karmat Ali area, Basrah Governorate, southern Iraq. The results revealed differences between them in the volatile compounds. A total of 65 peaks of volatile compounds were found in H. pulvialis, as the highest percentage was Hexadecanoic acid, ethyl ester, followed by 8-Heptadecene, n-Hexadecanoic acid, and Hexadecanoic acid, methyl ester. In the D. saline, 55 peaks of volatile compounds were recorded, such as 2 (4H)-Benzofuranone,5,6,7,7a-tetrahydro-4,4,7a-trimethyl-,(R)-, n-Hexadecanoic acid, Oleic Acid, Vitamin E, and other compounds.
