[Objective] The research aimed to study the scavenging effect of water extracts from Solen strictus,Sinonovacula constricta and Cultellus attenuatus on hydroxyl radicals(·OH) and superoxide anion radical(O2-·).[Method] The scavenging effects of water extracts from 3 species of razor shell on hydroxyl radicals were determined by using Feton system.The scavenging effects of water extracts from 3 species of razor shell on superoxide anion radical were determined by using pyrogallol autoxidation system.The scavenging effects on DPPH· were determined by using DPPH system.[Result] The scavenging effects of water extracts from 3 species of razor shell on ·OH,DPPH· and O2-· were all as follows: S.strictus S.constricta C.attenuatus.[Conclusion] The water extracts from the tissues of S.strictus and S.constricta had strong antioxidation.
