Progress on the bioactive components of medicinal and edible Nostoc species

Nostoc belongs to a genus of widespread cyanobacteria. Some species of Nostoc such as N. commune, N. sphaeroides and N. flagelliforme have been used as both food and medicine for centuries. Recent studies found a variety of bioactive substances derived from Nostoc species, including polysaccharides, proteins, lipids and pigments with antioxidant, anti-inflammatory, immunomodulatory and anti-tumor activities. This paper reviews the progress of the bioactive components of medicinal and edible Nostoc species, and provides an evidence for its further development and application.
