Eichhornia crassipes is one of the invasive and non-native aquatic plants of the Anzali wetland. In the present study, the effect of aqueous, aqueous-ethanolic (50:50), and ethanolic solvents was investigated on the amount of antioxidant properties of extracts obtained from different parts (leaf, stem, and root) of water hyacinth with Immersion (solvent) extraction method. Total phenol content, free radical scavenging activity, total antioxidant activity, and iron-reducing power were measured. The results showed that the highest amount of total phenol and the highest free radical neutralizing activity was related to the aqueous extract of the leaf, which had a significant difference from other treatments (P<0.05). The highest total antioxidant activity was related to the aqueous-ethanolic extract of the leaf, which had a significant difference from other treatments (P<0.05), and the highest iron reducing power was related to the aqueous extract of the leaf (P<0.05). The extract obtained from the leaf had higher antioxidant properties than the stem and root. According to the results, aquatic water hyacinth can be used as a cheap and suitable natural antioxidant source.
