| This study compares the antioxidant activity and phenolic content of extracts of four mollusk species (Oyster rock bivalve; Saccostrea cuculate, cabbage bivalve; Callista umbonella and Molok or cylindrical clam; Solen vagina and edible snail; Ampullaria cuprina) and determine the best mollusk in Qeshm coast. Mollusc species (n=100 for each mollusk) were stored in cold boxes with ice and transferred to the laboratory after collection. The samples were well ground and aqueous, ethanolic (90% ethanol) and hydro-ethanolic (50:50) extracts were prepared from them. The results showed that the highest amount of phenolic content (81.66 mg GAE/g extract), diphenylpicrylhydrazyl (DPPH) antiradical activity (1722.66 µmol Trolex /g extract) and antiradical activity equivalent to Trolex (649.33 µmol Trolex/g) extract) was observed in the ethanolic extract of edible snail. Also, the amount of antioxidant activity was maximum in three methods: PMP, 606.66 µmol Trolex, FRAP: (740 µmol iron/ gram of extract and RP: 1.24 in edible snail. Aqueous, ethanolic and hydro-ethanolic extracts of four Mollusca species showed different levels of antioxidant activity in all studied models. In general, ethanolic extract of edible snail showed the best antioxidant activity and phenolic content, which can be considered as rich sources of natural antioxidants for food usage is recommended |
