Porphyra sensu lato belongs to Bangiales, the most genetically diverse order of red algae. Porphyra or Pyropia is widely cultivated in East Asian countries, such as China, Japan, and Korea. Dried Porphyra contains numerous nutritional and biofunctional compounds, including proteins, minerals, dietary fiber, polyunsaturated fatty acids, carotenoids, saccharides, and mycosporine-like amino acids. In addition, the compound is most abundant in Porphyra, such as polysaccharides and phycobiliproteins, and demonstrates various immunomodulating, anticancer, antihyperlipidemic, and antioxidative activities. This review summarizes our current knowledge concerning the pharmacologically active substances found in Porphyra species. The biological activities and potential applications of certain carbohydrates, proteins, peptides, and other small molecules purified from Porphyra are also described, and possible areas for future studies are discussed.
