Abstract: Using mice as experimental objects, we observed effects of the Liquan powder on mice weight increase, loading swimming time, pole-climbing time, atmospheric oxygen absence resistant effect, water labyrinth test, and also on mice hemoglobin, sean LDH activity, serum total protein,blood sugar, serum urea nitrogen lipofuscin, weight ratio of immune organs to body,etc. The results showed that experimental group could increase mice weight (P<0. 05 or P<0. 01 ), lncrease poleclimbing time and oxygen absence resistance time (P<0. 05), increase content of serm total protein,blood sugar, serun LDH (P<0. 05 ), decrease liver lipofuscin content (P<0. 05) and increase the weight ratio of spleen and thymus to body. Hints: the Liguan powder could stimulate mice weight increase,raise endurance of organism, increase responsibility of organism and have obvious fatigue resistance. It also had effects on memory and immune function enhancement and senility resistance.

Key words: Liguan powder Fatigue resistance Oxygen absence resistance Immune function Senility resistance
