Abstract
The N4-acetyl derivatives of sulfaquinoxaline and suifadimethoxine were stable in fortified chicken liver and thigh muscle tissues during frozen storage for 1 year at –20 and –70°C. In contrast, the parent compounds depleted approximately 35% in liver tissues at –20°C. The transformation of the depleted sulfa drugs to their N4-glucopyranosyl derivatives was negligible, suggesting that products other than glucosides resulted during the storage period.Keywords
