Acrostichum aureum is a perennial mangrove fern with horizontally growing massive rhizome. Nutritional and physicochemical characteristics of the rhizome and extracted starch was examined. The rhizome was found to be a rich source of starch and essential nutrients like protein, fiber, ash, and minerals. The rhizome had 53% starch. Starch granules showed variation in shape and sizes. Amylose content of the starch was 24%. The pH of the starch was slightly acidic. Physicochemical and nutritional studies indicated that fern starch can be used as food substitute and for the pharmaceutical application.
