Biomineral characterization and phytochemical profile of green algae Halimeda macroloba and Halimeda opuntia from coastal waters of Tanjung Merah, Bitung City, North Sulawesi, Indonesia

This study aims to determine the mineral composition in green algae Halimeda macroloba and H. opuntia. The scanning electron microscope analysis and energy dispersive were used to show the morphology of the particles and the mineral composition contained in these algae. The scanning electron microsc...

Summary:This study aims to determine the mineral composition in green algae Halimeda macroloba and H. opuntia. The scanning electron microscope analysis and energy dispersive were used to show the morphology of the particles and the mineral composition contained in these algae. The scanning electron microscope analysis showed the particle morphology of H. macroloba and H. opuntia. Enlargement of H. macroloba nanoparticle images was carried out on a scale of 1,000x, 5,000x, 10,000x, 20,000x, and 200,000x, while enlargement of H. opuntia was 1,000x, 5,000x, 10,000x 20,000x, and 50,000x. Specimens analysis using energy dispersive showed that the two green algae H. macroloba and H. opuntia contained the following biomineral compound elements O>Na>Ca>Cl and O>Ca>C, respectively. H. macroloba has 24 major phytochemical compounds and at least five of the highest peaks were heptadecanoic acid, 16-methyl-, methyl ester, n-hexadecanoic acid, hexadecanoic acid, methyl ester, 1-chloroundecane, and eicosanoic acid. H. opuntia has 55 major phytochemical compounds and at least five of the highest peaks were phytol, neophytadiene, 9,10-secocholesta-5,7,10(19)-triene-3,24,25-triol, (3ß,5Z,7E), ethyl iso-allocholate, hexadecanoic acid, and ethyl ester.
