Description

Isoquercitrin is known to be an antioxidant substance. Isoquercitrin was administered to diseased pearl oyster affected by “akoya oyster disease” to confirm its recovery effect. Pearl oysters were incubated in each of 4 tanks containing respectively, 0, 2, 4 and 8 ppm isoquercitrin for 10 days at 25°C. As the result, isoquercitrin controlled the hemocytes collapse and reduced discoloration of adductor muscle of the diseased pearl oyster. Therefore, it is postulated that isoquercitrin reduced radical damage caused by “akoya oyster disease (A.O.D.)”.
