Determination of total phenolic and total flavonoid contents and antioxidant capacities of an aquatic plant (Riccia fluitans)

14503

Riccia fluitans, whose common name is crystalwort, is an aquatic floating plant of the liverwort genus Riccia which is popular among aquarist plants. It can be found floating in ponds, and often forms thick mats on and under the water surface.The objective of this study made to determine the antioxidant activities of Riccia fluitans using different in vitro methods. For evaluation of antioxidant and antiradical activities, ABTS•+ (2,2´-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid)) radical scavenging activity, DPPH• (1,1-diphenyl-2-picryl-hydrazyl) free radical scavenging activity, reducing power, and ferrous ions chelating activities were calculated. α-tocopherol were used as the reference antioxidant compound. In addition, the total phenolic and total flavonoid compounds in ethanol extracts were determined as gallic acid and quercetin equivalents, respectively. Consequently, this plant is a promising source of natural food antioxidants.
