Purple sweet potato is rich in anthocyanins. It is well known that anthocyanins have a variety of biological activities including anti-oxidant, anti-inflammatory, anti-tumor. In this study, the effects of purple sweet potato powder (PSPP) on memory in juvenile mice were examined. When mice were fed a large quantity (25.5% of diet) of PSPP, they showed impaired memory. But the mice fed a small quantity (5% of diet) of PSPP showed enhanced memory. These results suggests that excessive amount of anti-oxidant may affects the development of nervous system and impaired memory, but adequate amount of anti-oxidant improve memory in juvenile mice.
