The effect of feeding Katha (Acacia catechu) on niacin, riboflavin and ascorbic acid status in rats was investigated. The riboflavin content of blood and liver and its urinary excretion are not affected. Initially, the excretion and tissue content of ascorbic acid increases slightly, but eventually it returns to normal. The feeding of katha to rats is accompanied by a significant decrease in the niacin content of blood and liver as well as its excretion.
