Methods The immune functions were investigated by measuring thymus and spleen indices, celiac macrophage phagocytic index, and phagocytic rate from normal mice which were ig administered with Alpine-TLBP (50, 100, and 200 mg/kg) everyday, respectively; The clearing effect of Alpine-TLBP on hydroxyl radical was measured by salicylic acid capture method; The clearing effect of Alpine-TLBP on superoxide anion free radical was measured by pyrogallol auto oxidation method. Results Alpine-TLBP among 50—200 mg/L could significantly enhance thymus and spleen weight, viscera index, and celiac macrophage phagocytosis; Alpine-TLBP had a significant effect on clearing hydroxyl radical and superoxide anion radical, Alpine-TLBP among 50—500 μg/mL has dose-response relationship on the effect of clearing hydroxyl radical and superoxide anion radical, and the IC50 were 142.2 μg/mL and 203.2 μg/mL, respectively. Conclusion Alpine-TLBP can enhance normal mouse immunological function, and has strong ability of clearing hydroxyl radical and superoxide anion radical."/>
