Table 2. Antioxidative properties of N. commune.

	Bioactives	Key effects	Ref.
polysaccharides		1. O2·− scavenging capacity value was higher by 54.8% and 103.7%, respectively, compared to Nostoc flagelliforme and Nostoc sphaeroides Kütz.	[43]
		1. Increase the antioxidase activity in Caenorhabditis elegans. 2. Decrease the lipid peroxidation level in Caenorhabditis elegans. 3. Paraquat-induced oxidative damage reducation in Caenorhabditis elegans.	[6]
total flavonoids		1. Higher antioxidative ability than those of polysaccharides and fat-soluble components.	[49, 51]
glycosylated mycosporine-like amino acids (MAA)	1050-Da MAA	1. Approximate 27% contribution of the total radical scavenging activity in the water extract of N. commune.	[17]
