Age-related changes of ascorbic acid content of liver and brain of common Indian toad, Bufo melanostictus

Ascorbic acid content reaches a peak level in liver in group III male toads and then declines significantly. But there is no significant age-related change in ascorbic acid in the brain of male toads or in liver and brain of female toads. Sex comparison indicates that in females the content declines in the liver of age-group III and increases in age-group II, and there is an increase in the brain of age-group III females over their male counterparts.
