Abstract The antifatigue effects of the hot‐water extract longan ( Dimocarpus Lour.) seeds were studied in mice. Longan seed polysaccharides administered at doses 50, 100, 200 and 400 mg/kg activity was evaluated using a swimming test, along with determination serum urea nitrogen, hepatic glycogen blood lactic acid content. results show that polysaccharides, ranging from 50 to 100 mg/kg, extended time, increased p < 0.01, n = 10), reduced nitrogen 10) decreased Therefore may have potential as an agent.
